A direct alkylation of unprotected glycosyl fluorides under mild basic conditions without affecting the anomeric group is reported. Thus peralkylated glycosyl fluorides, applied in Lewis acid catalyzed glycosylations, are now effectively available from the starting sugar in two simple steps.
据报告,在温和的碱性条件下,未保护的糖基
氟化物可以直接烷基化,且不影响其异构体。因此,在
路易斯酸催化糖基化反应中应用的过烷基化糖基
氟化物,现在可以通过两个简单的步骤从起始糖有效制备。
