摘要：
[GRAPHICS] The conjugate additions of titanium enolates of glycolate-derived chiral oxazolidin-2-ones to various Michael acceptors have been evaluated as an entry to enantiopure 1,2,5-trioxygenated and related synthons. alpha,beta-unsaturated Weinreb and morpholine amides do react under suitable conditions and their adducts can be converted to diverse C1-C5 chiral fragments.
