Thiophenyl-glycosides allylation

C-Glycosides. Thiophenyl glycosides undergo ready free-radical allylation with allyl- or methallyltri- -butyltin. Thus the L-lyxose derivative 1 reacts with allyltri-/ -butyltin under photochemical initiation to give 2 and 3 in the ratio 90 10. The reaction... [Pg.23]

An additional example illustrating the utility of thiophenyl glycosides in free radical mediated C-glycosidations was reported by Waglund, et a/.6 As shown in Scheme 5.2.4, 1-methylcarboxy-l-phenylthioglycosides were treated with allyltributyltin and irradiated with ultraviolet light. The resulting C-allyl derivatives were formed in approximately 30% yields with the stereochemical... [Pg.183]
