  Synthesis of Galacto- and Mannosucroses

  摘要：

  A concise synthesis of beta-D-fructofuranosyl alpha-D-galactopyranoside (2), and beta-D-fructofuranosyl alpha-D-mannopyranoside (3) is described. Inversion of the C-3 alpha-hydroxy group of alpha-D-galactopyranosyl and alpha-D-mannopyranosyl beta-D-psicofuranosides 10 and 11 via oxidation and stereoselective reduction furnished the corresponding beta-D-fructofuranosides in excellent yields.
