Allyl(All) and Allyloxycarbonyl(Alloc) amino-acid derivatives are deprotected through palladium-catalyzed hydrostannolysis by Bu3SnH in a highly selective manner.Benzyl and benzyloxycarbonyl groups are stable under these conditions.Moreover the allyl and Alloc groups seem orthogonal to the t-butyl and t-butoxycarbonyl protecting groups.
