  Silica gel-catalyzed β-O-glucosylation of alcohols with 1,2-anhydro-3,4,6-tri-O-pivaloyl-α-d-glucopyranose

  摘要：

  1,2-Anhydro-3,4,6-tri-O-pivaloyl-alpha-D-glucopyranose (1a) was allowed to react with alcohols in the presence of solid acids such as silica gel and zeolite HY, to afford beta-O-glucosides stereoselectively. Several natural glucosides were synthesized by the application of the present reaction. (C) 1997 Elsevier Science Ltd.
