A convenient one-step RhCl3-catalyzed deprotection of acyclic N-allyl amides is described. Reactions of RhCl3 with n-PrOH provide an active rhodium hydride species to catalyze isomerization of N-allyl amides to corresponding enamides and generate a crucial catalytic amount of HCl to convert the enamides to deallylated amides through N,O-acetal exchange.
