The synthetic utility of the N-(allyloxycarbonyl) (Alloc) substituent in alpha-amino acid derivatives is substantially extended beyond its well-known function as an amine protecting group. When the palladium-catalyzed deprotection is carried out by using tributyltin hydride as nucleophile (the Guibe...
