In the two title optically active tetra­hydro­iso­quinoline derivatives, namely 3-hydroxy­methyl-4-phenyl-1,2,3,4-tetra­hydro­isoquinolin-2-ium bromide methanol hemisolvate, C16H18NO+·Br-·0.5CH3OH, (IIb), and 2-formyl-3-hydroxy­methyl-4-phenyl-1,2,3,4-tetra­hydro­iso­quinoline, C17H17NO2, (III), the absolute configurations have been confirmed as 3R,4R by structure refinement using Bijvoet-pair reflections. The hydroxy­methyl and phenyl groups in (IIb) are oriented in equatorial and pseudo-equatorial positions, respectively, whereas in (III), the corresponding groups are in axial and pseudo-axial positions, respectively; the hydroxy­methyl and phenyl groups are trans with respect to one another in both structures. The heterocyclic rings in (IIb) and (III) adopt envelope conformations inverted with respect to each other. In both structures, the mol­ecules are linked through hydrogen bonds.

Comment top

One of the steps in our synthesis of 4-phenyl-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (4-phenyl-Tic), (IV), from (+)-thiomicamine, (I), involved N-formylation of the intermediate 3-hydroxymethyl-4-phenyl-1,2,3,4-tetrahydroisoquinoline hydrobromide, (IIa), to give 2-formyl-3-hydroxymethyl-4-phenyl-1,2,3,4-tetrahydroisoquinoline, (III) (Brózda et al., 2000; see Scheme). The absolute configuration of both compounds, i.e. of (IIa) and (III), as 3R,4R was implied by the 1S,2S configuration of the starting material (+)-thiomicamine, (I), and mechanistic considerations (Brózda et al., 2000).

A half-chair or envelope conformation with a trans equatorial–pseudo-equatorial orientation of the C3 and C4 substituents in (IIa), respectively, was confirmed by the value of the coupling constant (J = 10.2 Hz) between atoms H3 and H4 in the 1H NMR spectrum. This value corresponds to that of axial–pseudo-axial H atoms in cyclohexene derivatives (Ehil & Wilen, 1994) and also to those in other trans-3,4-disubstituted tetrahydroisoquinoline derivatives (Bohe et al., 1999; Pedrosa et al., 2001).

In the 1H NMR spectrum of formamide (III), however, atoms H3 and H4 appear as singlets, suggesting a conformational inversion within the hydrogenated heterocyclic ring. We suspected that intramolecular hydrogen bonding involving the hydroxyl H and amide O atoms was responsible for this change (Brózda et al., 2000). Such a ring inversion would then place these H atoms in equatorial–pseudo-equatorial positions, respectively, with a torsion angle θ of ca 90°, for which, according to the Karplus equation, 3J 0. There was also a possibility of steric hindrance between the C3 substituent and the introduced N-formyl group, resulting in a change of conformation. In order to solve this problem, X-ray single-crystal analyses were performed on compounds (IIb) and (III).

The asymmetric unit of (IIb) contains one 3-hydroxymethyl-4-phenyl-1,2,3,4-tetrahydroisoquinoline molecule in the form of its ammonium cation (i.e. with an NH2+ group), a Br- anion and half a methanol molecule. In compound (III), the asymmetric unit contains two independent 2-formyl-3-hydroxymethyl-4-phenyl-1,2,3,4-tetrahydroisoquinoline molecules.

The results obtained for the title compounds confirm the absolute 3R,4R configuration of both compounds proposed earlier on the basis of 1H NMR studies (Brózda et al., 2000). Moreover, upon formylation of (II), the distorted envelope conformation of the heterocyclic ring in the tetrahydroisoquinoline system [Cremer & Pople (1975) puckering parameters for (IIb): Q = 0.512 (3) Å, Θ = 132.4 (3)° and Φ = 131.9 (5)°; for (III): Q = 0.446 (2) Å, Θ = 52.1 (3)° and Φ = 310.6 (3)° (molecule A), and Q = 0.469 (2) Å, Θ = 53.5 (2)° and Φ = 302.1 (3)° (molecule B)] has undergone inversion, leading to a change in the mutual orientation of the substituents at C3 and C4. The deviation of atom C3 from the almost planar system of the other five atoms of the heterocyclic ring is 0.691 (4) Å for (IIb), 0.611 (2) Å for molecule A of (III) and 0.646 (2) Å for molecule B of (III) (Sheldrick, 1997). In (IIb), the substituents at C3 and C4 have a mutually trans equatorial–pseudo-equatorial orientation, but in (III), they have a trans axial-pseudo-axial orientation. A similar stereochemistry of the partially reduced isoquinoline core of (IIb) and (III) seems to be preserved in solution, as may be judged from the values of the coupling constants in their 1H NMR spectra (see above). In (IIb), the torsion angle C11—C3—C4—C13 [-58.5 (3)°] indicates a synclinal conformation of the C11 atom in the hydroxymethyl group with respect to the C13 atom of the phenyl group, while in (III), the analogous angle C13—C3—C4—C15 [-157.89 (16)° (molecule A) and -161.42 (14)° (molecule B)] reveals a mutual orientation between anticlinal–antiperiplanar for atoms C13 and C15. It can be concluded that the above-mentioned inversion of the conformation of the hetrocyclic ring in the partially reduced isoquinoline core occurred as a result of a steric hindrance between the C3-hydroxymethyl substituent and the N-formyl group or/and a change in the state of hybridization of atom N2, which suggests a considerable contribution of the ionic form in the resonance hybrid of the amide group. The N2—C11 bond distance [1.324 (3) Å (molecule A) and 1.318 (2) Å (molecule B)] is somewhat shorter than a tertiary amide distance [1.346 (5) Å; Allen et al., 1987]. The sum of the valence angles around N2 is 359.8 (3)° for molecule A and 359.6 (3)° for molecule B.

In (IIb), the methanol solvate molecule lies near the twofold rotation axis, showing orientational disorder (see Experimental).

The hydroxyl group in molecule A of (III) also exhibits orientational disorder. Both positions of the hydroxyl group favour the formation of an intermolecular hydrogen bond with atom O12 of the carbonyl group of molecule B (Table 2).

In the crystal lattice of (IIb), the Br- anion is involved in three hydrogen bonds as an H-atom acceptor. In these bonds, the H-atom donors are the N2 atoms from two different molecules and atom O12 of the hydroxyl group belonging to the third molecule (Table 1). Additionally, there is a possible intermolecular C—H···O hydrogen bond (Table 1). In this way, chains are formed parallel to the y axis.

In the crystal lattice of (III), the A and B molecules are connected by hydrogen bonds (O141···O12Bi, O142···O12Bi and O14B···O12Aii; see Table 2 for symmetry codes), forming chains parallel to the y axis. A comparison of IR absorption in spectra of (III), recorded in the solid state (KBr) and in solution (CH2Cl2), suggests the existence of similar intermolecular interactions in both phases.

Experimental top

Compounds (IIb) and (III) were prepared according to the method of Brózda et al. (2000). Crystals of both compounds suitable for single-crystal X-ray diffraction analysis were selected directly from the analytical samples.

Refinement top

The positions of the H atoms bonded to N and O atoms in the partially reduced isoquinoline core of (IIb) were obtained from difference Fourier maps and were refined freely. For molecule A of (III), the hydroxyl group, which was disordered over two positions (O141 and O142, with occupation factors of 67 and 33%), was allowed to rotate freely around the C—O bond. Atoms H141/H142 was placed geometrically and they converged to a position that could be interpreted as a favourable conformation for the formation of a hydrogen bond. The remaining H atoms of (IIb) and (III) were positioned geometrically and refined with a riding model (O—H = 0.82 Å and C—H = 0.93–0.98 Å) and with Uiso values constrained to be 1.5 (for hydroxyl H atoms) or 1.2 (for all other Hatoms) times the Ueq value of the parent atom.

In (IIb), the methanol solvate molecule lies near the twofold axis and shows orientational disorder; the equivalent isotropic displacement parameter of atom O19 is high [0.211 (5) Å2], and is associated with an interatomic O19—C20 distance [1.247 (14) Å] shortened by about 11σ relative to the normal value for a Csp3—O single bond [1.413 (4) Å; Allen et al., 1987]. The position of atom O19 was fixed on the twofold axis, and atom C20 was introduced with a site-occupation factor of 50%. A significant degree of disorder of the methanol solvate molecule prevents identification of the positions of the H atoms, so making it difficult to perform a correct determination of the positions of the O and C atoms in the molecule. Nevertheless, the assumption of the inverse positions of the atoms leads to worse results.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
