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 asymmetric unit of the title compound, C 19 H 16 FN 5 O 4 , contains two independent molecules. The dihedral angles between the main planes and the fluorophenyl rings in the two molecules are 83.24 (5) and 71.76 (4) . Weakstacking interactions may be effective in the stabilization of the crystal
The title compound, C 23 H 25 BrO 3 , was synthesized by the reaction of p-bromobenzaldehyde with dimedone and HClO 4 / SiO 2 in EtOH. In the molecule, the dihydropyran ring adopts a boat conformation and the two cyclohexene rings are in a trans conformation.
