Palladium-catalyzed stereoselective C-glycosidation of unprotected enones derived from d-glucal with trimethylsilyl cyanide
摘要:
Acetylated and unprotected enones derived from D-glucal reacted with trimethylsilyl cyanide in the presence of a catalytic amount of a palladium compound in 1,4-addition fashion to afford the corresponding 3-keto-glycosyl cyanides in high yield and in high alpha-selectivity.
