权利人:LILLY CO ELI
摘要:A process for recycling the difluoro sugar in the synthesis of 2,2-difluoronucleosides proceeds by removing the base moiety of alpha -difluoronucleosides by reduction and hydrolysis, followed by oxidation to put the difluro sugar in a form conventiently recycled into the synthesis, and intermediates useful therefor.

摘要:A process for recycling the difluoro sugar in the synthesis of 2,2-difluoronucleosides proceeds by removing the base moiety from α-difluoronucleosides by reduction and hydrolysis, followed by oxidation to put the difluoro sugar in a form conveniently recycled into the synthesis, and intermediates useful therefor.
