โœฆ Synopsis

The molecule of the title compound, C~23~H~23~NO~4~S, adopts a folded conformation, with the cyclopentadienone ring and tosyl groups arranged in an almost face-to-face fashion. The pyrrolidine ring has an envelope conformation and the dihydropyran ring is in a half-chair conformation. The pyrrolidine and dihydropyran rings are cis-fused. The indenone ring system is essentially planar, and the indene plane forms a dihedral angle of 25.12โ€…(3)ยฐ with the sulfonyl-bound benzene ring. In the crystal structure, molecules translated by one unit cell along the a-axis direction are linked into a chain by Cโ€”H...O hydrogen bonds. The inversion-related molecules of adjacent chains are linked along the c axis by Cโ€”H...O hydrogen bonds into a sheet-like structure parallel to the ac plane.

The asymmetric unit of the title compound, C 26 H 30 N 2 O 4 S, consists of two independent molecules, A and B, with similar conformations. In both molecules, the pyrrolidine and dihydropyran rings adopt envelope conformations, and are trans-fused; the tosyl group is attached to the pyrrolidine ring

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
