An asymmetric synthesis of the highly oxygenated cyclopentanoid antibiotic (+)-kjellmanianone (1) has been achieved.The key step entailed enantioselective hydroxylation of the prochiral sodium enolate of β-keto ester 2 with the new, enatiomerically pure N-sulfonyloxaziridine 7b, affording 1 in 68.5percent ee (60percent yield).Possible transition state structures for the asymmetric oxidation are evaluated.

New, more efficient enantiomerically pure (camphorylsulfonyl)oxaziridines are prepared by mono alkylation of the dianion of (camphorylsulfonyl)imine at the carbon atom adjacent to the sulfonyl group.
