An asymmetric aminohydroxylation approach to the stereoselective synthesis of cis-substituted azetidinone of loracarbef
摘要:
A formal synthesis of loracarbef is described. The required key cia-substituted azetidinone skeleton was stereoselectively constructed via p-amino acid, which was provided from the asymmetric aminohydroxylation of alpha,beta -unsaturated ester. (C) 2001 Elsevier Science Ltd. All rights reserved.
