The asymmetric unit of the title compound, C~22~H~29~N~3~O~5~S, contains two independent molecules, __A__ and __B__, which differ slightly in the orientation of the ethyl and tosyl groups with respect to the attached pyrrolidine ring, as evidenced by the relevant torsion angles. In both molecules, t
The title compound, C~22~H~29~NO~4~S, crystallizes with three independent molecules, __A__, __B__ and __C__, in the asymmetric unit. Each of the three independent molecules adopts a folded conformation, with the phenylsulfonyl group lying over the pyranocyclohexanone ring system, and with the pyrrol
The title compound, C 21 H 20 ClN 3 O 2 , was synthesized by the reaction of 4-chlorobenzaldehyde and 3-(5,5-dimethyl-3-oxocyclohex-1-enylamino)propanoic acid with malononitrile in ethylene glycol under microwave irradiation. The dihydropyridine ring has a boat conformation. The pyrimidine ring adop
