(E)-Methyl 2-[(2-formyl-6-meth­oxy­phen­oxy)meth­yl]-3-phenyl­acrylate

The title compound, C₁₉H₁₈O₅, crystallizes with two independent mol­ecules (A and B) in an asymmetric unit in both of which the two aromatic rings are in a bis­ectional orientation as evidenced by the dihedral angle between them [41.7 (1)° in mol­ecule A and 35.6 (1)° in mol­ecule B]. Both mol­ecules adopt an E configuration with respect to the C=C bond. An intra­molecular C—H...O hydrogen-bond occurs in mol­ecule A. The crystal packing features inter­molecular C—H...O inter­actions.

Methyl (E)-2-[(2-nitro­phen­oxy)meth­yl]-3-phenyl­acrylate

The title compound, C₁₇H₁₅NO₅, adopts an E conformation with respect to the C=C double bond of the phenyl­acrylate unit. The phenyl ring and methyl acrylate group of the phenyl­acrylate unit are disordered over two sets of sites with site-occupancy ratios of 0.705 (5):0.295 (5) and 0.683 (3):0.317 (3), respectively. The mean plane through the benzene ring of the phenyl acrylate makes dihedral angles of 88.4 (8) (major component) and 86.7 (8)° (minor component) with the nitro­phen­oxy ring; the dihedral angle between the two components is 3.64 (6)°. Intra­molecular C—H...O interactions stabilise the molecular structure. In the crystal, C—H...O inter­actions result in a chain of mol­ecules running along the b axis.
