| Abstract/Notes | The title compound, C22H29NO4S, 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 pyrrolidine and dihydropyran rings cis-fused. In all three molecules, the pyrrolidine ring has a twist conformation and the dihydropyran ring is in a half-chair conformation. The cyclohexenone rings adopt envelope conformations, with the flap atom puckered towards the phenylsulfonyl group in molecule A, and away from that group in molecules B and C, resulting in a different overall conformation for molecule A compared to B and C. In all molecules, the tosyl group is equatorially attached to the pyrrolidine ring. In the crystal structure, the molecules are linked into a three-dimensional framework by C—H...O hydrogen bonds. |
