| Abstract: | 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. |
