32 - 064Lewis Acid Promoted Transesterification of N-Acyl Oxazolidinonesunder Mild Conditions. — In the presence of mild Lewis acid catalystsTLA, MgBr2, or Sc(O-Tf)3 N-acyl oxazolidinones are smoothly converted tothe corresponding methyl esters. The mild conditions suppress racemizationof chiral substrates and methanolysis of acid-sensitive groups. — (ORITA,AKIHIRO; NAGANO, YOSHIFUMI; HIRANO, JUNICHI; OTERA, JUNZO;Synlett (2001) 5, 637-639; Dep.
