Two diastereoisomers of 2-(benzenesulfonyl)-5-benzoyl-1-oxo-3-phenyl-2,5-diazaspiro[3.4]octan-7-yl acetate

The structures of two diastereoisomers of the title compound, C27H24N2O6S, were determined by single-crystal diffractometry. The two molecules are very similar as far as bond distances and angles are concerned, but more substantial differences are observed in some torsion angles.
