  摘要：

  E-(5-N-phthaloyl)-2-pentenoic acid benzyl ester was dihydroxylated by a Sharpless AD-mix protocol followed by mononosylation of the resultant 2R,3S diol. Azide displacement of the mononosylate followed by protection with the TBDMS group gave the epsilon-N-phthaloyl-substituted-beta-tert-butyldimethylsilyloxy-alpha-azidocarboxylic acid benzylester. Hydrazinolysis resulted in removal of the phthalimide group with concomitant lactamization to the 4-silyloxy-3-azidopiperidinones. Staudinger reduction of the azidopiperidinones followed by N-phthaloylation and hydrolysis of the silyl group afforded the 4'-hydroxylated-6'-deoxythalidomide derivatives.
