SYNTHESIS OF GALACTO- AND MANNOSUCROSES

摘要

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