Abstract

Nucleophilic additions to D-isolevoglucosenone are face selective and generate the corresponding enolates which react with 1,2:3,4-di-O-isopropylidene-alpha-D-galacto-hexodialdo-1,5-pyranose to give aldol adducts. These can be reduced stereoselectively into C(1-->3) glycosides of 1,6-anhydro-D-galacto-pyranose. (C) 1997 Elsevier Science Ltd. All rights reserved.
