Methyl 2-methyl-5-oxo-4-(2-thienyl)-1,5,7,8,9,10-hexahydro-4H-pyrido[2',3':3,4]pyrrolo[1,2-a][1,3]diazepine-3-carboxylate

Abstract: The crystal structure of the title compound, C₁₈H₁₉N₃O₃S, is formed by single molecules linked by N-HO hydrogen bonds into infinite linear chains along the ac diagonal. The thiophene ring is nearly planar and is approximately perpendicular to the mean plane of the 1,4-dihydropyridine ring. The ester group has a trans geometry with respect to the adjacent ring double bond. The dihydropyridine and pyrrole rings are coplanar.
