The 3,4-trans-4,5-trans-2-amino-3-cyano-1,3-dimethyloxycarbonyl-4,5-di-(3,4-methyl-enedioxylphenyl) cyclopentene has been synthesized and characterized by IR, H-1 NMR, Elemental analysis, and X-ray crystallography. It crystallizes in the monoclinic space group P2(1)/n, with a = 10.936(3) Angstrom, b = 10.142(3) Angstrom, c = 20.001(4) Angstrom, beta = 93.81(2)degrees, and D-calc = 1.390 g cm(-3) for Z = 4. X-ray analysis reveals that the phenyl groups and the alkoxyl carbonyl group are in the equatorial positions. The dihedral angles between the phenyl groups and the central five-membered ring are 73.08degrees and 62.15degrees. In addition, there are intermolecular hydrogen bonds in the crystal lattices.
