  描述：

  2,3,6-tri-O-pivaloyl-β-D-glucopyranose 在 caesium carbonate 作用下， 生成 androst-4-en-3-on-17-β-yl 2,3,6-tri-O-pivaloyl-β-D-glucopyranoside

  A novel synthesis of protected glucose intermediates.

  摘要：

  The 1,2,4,6-Tetra-O-pivaloyl-D-gluco-pyranose 3 and 1,2,3,6-Tetra-O-pivaloyl-D-glucopyranose 4 have been prepared in one step from anhydrous glucose and pivaloyl chloride. These new intermediates can be converted into the corresponding esters, or used in the synthesis of a disaccharide in good yield. Thus, 2,3,6-Tri-O-pivaloyl-gluco-pyranose 10 can be prepared from 4, and used for preparation of beta-gluco derivatives via the corresponding trichloroacetimidate 12.
