Abstract
The gem-difluoronucleosides 1 and 2, pyranosyl analogues of gemcitabine, ha ve been synthesized from D-mannose and D-glucose respectively. The key step s were the formation of the difluoromethylene group by reaction of the corr esponding ulose with DAST, and the glycosylation. (C) 1999 Elsevier Science Ltd. All rights reserved.
