[reaction: see text] The solid-phase synthesis of N-alkyl-beta-keto)amides and 1,2,4,5-tetrasubstituted imidazoles was demonstrated using a traceless cleavage strategy based on benzylic acylammonium chloride reactivity. The approach enables the assembly of diverse compounds in a minimal number of steps in moderate to excellent yield (23-88%) and high purity (64-100%).
