Phenacyl-Directed Alkylation of Imidazoles: A New Regiospecific Synthesis of 3-Substituted L-Histidines

A new strategy for regiospecific imidazole alkylation of suitably protected histidines is described wherein a phenacyl group serves as a protecting group of the distal imidazole nitrogen atom.Alkylation of N-BOC-1-phenacyl-L-histidine methyl ester at N(3)
