Abstract
We report the crystal structure of (1R,3R)-2[(2R,4R,5R)-3-(p-chlorophenylsulfonyl)-4-methyl-5-phenyl-1,3-oxazolidin-2-yl]-5-{2-(1R,2S)-[(2R,4R,5R)-3-(p-chlorophenylsulfonyl)-4-methyl-5-phenyl-1,3-oxazolidin-2-yl]-1-hydroxycyclopentyl}-1-cyclopentanone, C 42 H 44 Cl 2 N 2 O 8 S 2 (1). The chlorophenyl-sulfonyl substituent is cis to the phenyl ring on each oxazolidine heterocycle. Each chlorophenyl-sulfonyl substituent adopts a folded conformation by which the aromatic ring shields the heterocycle. The oxazolidine rings have envelope conformations with C(3) and O(17) out of their respective planes
