摘要
Highly efficient removal of allyloxycarbonyl (Alloc) group was achieved in the presence of CH3COONH4, Pd[P(C6H5)3]4, and NaBH4 in MeOH-THF, within 5 min in almost quantitative yields (〉90%, isolated yield) without affecting acetyl, benzoyl, isopropylidene, benzylidene, allyl, benzyl, benzyl carbonate, or azido groups.
