Recently, we reported an efficient chemical method for the synthesis of a variety of naturally occurring nucleoside diphosphate (NDP) sugars. This method, which is based on the cycloSal approach, can also be used, in principle, for the preparation of rare or even nonnatural NDP sugars. Herein, the syntheses of sulfoquinovose-, glucose-6-sulfate-, L-galactose-, and 2-fluoroglycopyranoside-containing NDP sugars are presented, as well as the synthesis of NDP sugars with non-natural nucleosides. The reactions described gave stereoisomerically defined NDP sugars in high yields and short reaction times.
