C«-Glycosylation procedures

The C-glycosylation procedures generally exploit the electrophilic character of the anomeric carbon of the sugar. The new C-C bond can be formed by reaction of the aldehydic function of the sugar with an organometallic or a Wittig... [Pg.59]

In C-glycosylation reactions a new stereocenter is formed, and in general only one of the two stereoisomers is desired. Therefore, it is quite important to develop stereoselective C-glycosylation procedures, in which the stereochemical outcome can be predicted... [Pg.61]

This article will describe our efforts in the stereoselective synthesis of C-glycosides of biological interest, giving, in the meantime, an overview of the main C-glycosylation procedures and explaining their stereochemistry. [Pg.61]
