Synthesis and Structural Conformation Studies of a Potent Unsymmetrical 1,4-Dihydropyridine.

Abstract  2,6-Dimethyl-5-(phenylcarbamoyl)-4-(3-nitrophenyl)-1,4-dihydropyridine-2-carboxylate was synthesized in two steps and was characterized spectroscopically and confirmed by X-ray diffraction studies. The molecule crystallizes in the monoclinic crystal class in the spacegroup P21/c with cell parameters a = 10.5960(6) Å, b = 10.2450(7) Å, c = 19.5790(11) Å, β = 107.448(3)° and Z = 4. The 1,4-dihydropyridine ring in the structure adopts a flattened boat conformation.
