(Received 1 December 2009; accepted 13 December 2009; online 19 December 2009)

The title compound, C26H28N2O9·1.5H2O, the product of an acid-catalysed Wagner–Meerwein skeletal rearrangement, crystallizes as a sesquihydrate with the O atom of one of the two independent water mol­ecules occupying a special position on a twofold axis. The organic mol­ecule comprises a fused penta­cyclic system containing two five-membered rings (cyclo­pentane and tetra­hydro­furan) and three six-membered rings (piperidinone, tetra­hydro­pyridine and benzene). The five-membered rings have the usual envelope conformations, and the central six-membered piperidinone and tetra­hydro­pyridine rings adopt boat and sofa conformations, respectively. In the crystal, there are three independent O—H⋯O hydrogen bonds, which link the organic mol­ecules and water mol­ecules into complex two-tier layers parallel to (001). The layers are further linked into a three-dimensional framework by attractive inter­molecular carbon­yl–carbonyl inter­actions.

Acid catalyzed Wagner-Meerwein rearrangement of substituted 3,8-dioxatricyclo[3.2.1.02,4]octanes (epoxy-7-oxabicyclo[2.2.1]heptenes) is used extensively in organic synthesis (Popp & McEwen,1958; Hogeveen & Van Krutchten, 1979; Hanson, 1991). However, with the exception of our works (Zubkov et al. 2004; Zubkov et al. 2009; Gurbanov et al. 2009), only a few examples of the skeletal rearrangement for 7-oxabicyclo[2.2.1]heptenes condensed with nitrogen-rings are known to date (Jung & Street, 1985; Keay et al. 1989). In particular, Wagner-Meerwein rearrangement in isoindolo[2,1-a]quinolines series has not been studied yet. The present work is meant to cover this gap. Hereunder, we report a new diastereoselective approach to 7,8-bis(acetyloxy)-5-R-7,9-epoxycyclopenta[4,5]pyrido[1,2-a]quinolines using 2-furyltetrahydroquinolines, readily accessible by Povarov reaction, as starting compounds (Zubkov et al. (2007)).

The structure of methyl 7,8-bis(acetyloxy)-11-oxo-5-(N-pyrrolidonyl)-7,9-epoxycyclopenta[4,5]pyrido[1,2-a]quinoline-10-carboxylate (I) was established by X-ray diffraction study (Fig. 1). Compound (I) crystallizes as sesquihydrate, i. e., C26H28N2O9.1.5H2O; one of the two independent water molecules occupies a special position on the twofold axis. Molecule of (I) comprises a fused pentacyclic system containing two five-membered rings (cyclopentane and tetrahydrofuran) and three six-membered rings (piperidinone, tetrahydropyridine and benzene). Both five-membered rings of the bicyclic fragment have usual envelope conformations, and the central six-membered piperidinone and tetrahydropyridine rings adopt the boat and sofa conformations, respectively. The nitrogen N12 atom has a trigonal-planar geometry (sum of the bond angles is 359.5°). The dihedral angle between the planes of the piperidinone (or rather "bottom of the boat" C6A, C7, C10A, C11 plane) and benzene is 38.81 (3)°. The two carboxylate substituents at the C7 and C8 carbon atoms are in the sterically unfavorable syn-periplanar configuration relative to the tetrahydrofuran ring. Such disposition is explained by the direction of the Wagner-Meerwein rearrangement.

The pyrrolidinone ligand and carboxylate substituent at the C10 atom are on the same side of the core pentacyclic framework. It is noteworthy that these fragments are engaged in the attractive intermolecular carbonyl-carbonyl interactions C13O1···C17i O3i and C19O5···C11ii O8ii [O1···C17i 2.947 (1) Å, O5···C11ii 2.993 (1) Å; symmetry codes: (i) -x, y, 1/2 - z; (ii) -x, 1 - y, 1 - z]. Carbonyl-carbonyl interactions of such type were investigated in substantial detail by Allen et al. (1998).

The molecule of (I) possesses eight asymmetric centers at the C5, C6A, C7, C7A, C8, C9, C10 and C10A atoms and can have potentially numerous diastereomers. The crystal of (I) is racemic and consists of enantiomeric pairs with the following relative configuration of the centers: rac-5S*,6aS*,7R*,7aR*,8R*,9S*,10S*,10aR*.

There are three independent H-bonds (Table 1), which link the molecules of (I) and water molecules into complex two-tier layers parallel to (001) (Fig. 2). The layers are linked further into three-dimensional framework by the above-mentioned attractive intermolecular carbonyl-carbonyl interactions.

Boron trifluoride etherate (0.3 ml, 2.4 mmol) was added to a solution of methyl (1aR*,2R*,3R*,3aS*,10R*,11aR*,11bR*,11cR*)-4-oxo-10-(2-oxopyrrolidin-1-yl)-1a,2,3,3a,4,11,11a,11c-octahydro-10H-2,11b-epoxyoxireno[6,7]isoindolo[2,1-a]quinoline-3-carboxylate (0.51 g, 1.2 mmol) in 15 ml of acetic anhydride. The mixture was stirred for 2 h at 296 K, then it was diluted with 100 ml of water and treated with a saturated solution of sodium carbonate until pH ~ 8–9. Organic products were extracted with chloroform (3 x 50 ml). The extract was dried (MgSO4), concentrated and purified by crystallization from hexane-ethyl acetate to give 0.41 g (0.8 mmol) of the polycycle (I) as colourless rhomboid-shaped blocks (Fig. 3). Yield is 67%. The single crystals of product (I) were obtained by slow crystallization from a mixture of 95% ethanol-DMF (yield 30%). M.p. = 460–462 K. IR, ν (cm-1): 1673, 1744 (NCO, CO2Me, COMe).

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.
