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.
