Glycosyl radicals, photochemical

The preparation of a variety of vinylic functionalized C-glycosides involves a photochemical reaction between telluroglycosides with aryl alkynes at 120 °C. Glycosyl radicals were initially formed by photohomolysis of the C-Te bond and readily added to the alkyne a vinyl telluride (e.g., 49) was finally obtained by a further attack of RTe- (Scheme 3.32) [82],... [Pg.88]
