  日期：2008.2.1

  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. α,β-unsaturated Weinreb and morpholine amides do react under suitable conditions and their adducts can be converted to diverse C1−C5 chiral fragments.
