Behaviour of the Primary Nitro Group Under Denitration Conditions
摘要:
Treatment of per-O-acetylated or acetalated glycosylnitromethanes derived from the common hexoses and pentoses with tributyltin hydride and a catalytic amount of a radical initiator [1,1'-azobis(cyclohexanecarbonitrile)] in refluxing benzene easily afforded the corresponding glycosylmethanal oximes in 84-97% yields. Per-O-acetylated C-beta-glycopyranosylmethanal oximes were employedfor synthesis of versatile C-beta-glycopyranosyl cyanides of the beta-D-gluco, beta-D-manno, beta-D-galacto, beta-D-xylo, and beta-L-rhamno configurations.
