(Z)-2-(3-hydroxy-4-methoxybenzylidene)-1-azabicyclo[2.2.2]octan-3-one.
Crystals of the title compound, C(15)H(17)NO(3), were obtained from a condensation reaction of 3-hydroxy-4-methoxybenzaldehyde with 1-azabicyclo[2.2.2]octan-3-one and subsequent crystallization of the product from methanol. The title compound, containing a double bond that connects the azabicyclic ring system to the 3-hydroxy-4-methoxybenzylidene group, was obtained with Z geometry.

The crystal structure of the title compound, C(15)H(17)NO(2), contains two nearly identical but crystallographically independent molecules, each with a double bond connecting an azabicyclic ring system to a 3-methoxybenzylidene moiety. The space group is triclinic P-1. The benzene ring is twisted by 18.44 (5) and 22.35 (4) degrees with respect to the plane of the double bond connected to the az...

In the title compound, C(16)H(12)O(4), the 1-benzofuran-one unit is in a planar conformation [C-C-C-C = 179.69 (12)°]. The conformation around the C=C double bond [1.3370 (17) Å] is Z. In the crystal, the mol-ecules are stabilized by O-H⋯O (running parallel to the bc plane) and C-H⋯O hydrogen bonds.

In the title compound, C(20)H(17)NO(4), the double bond of the acrylonitrile group separating the 1-benzofuran moiety from the 3,4,5-trimeth-oxy-phenyl ring has Z geometry. The 1-benzofuran groups are π-π stacked with inversion-related counterparts such that the furan ring centroid-centroid distance is 3.804 (5) Å. The dihedral angle between the planes of the trimeth-oxy-phenyl ring and the acr...
