In the title compound, C12H13NO2, the pyrrolidinone moiety is almost flat while the oxazole ring adopts an envelope conformation with the carbon atom bearing the phenyl substituent as the flap: the angle between the mean planes of the fused heterocyc

The chiral title compound, C8H15NO5S, was obtained by cyclization of (R)-1-(tert-butoxycarbonylamino)-2-propanol with thionyl chloride and subsequent oxidation with sodium metaperiodate/ruthenium(IV) oxide. It crystallizes with two independent molecu

In the title compound, the molecules stack parallel with the a axis with multiple H⋯O contacts involving the axial H and O atoms. Many more H⋯O contacts between the stacks exist, which mostly involve the equatorial hydrogen and oxygen atoms. Th
