Intermolecular alkylation of the aziridinyl oxazole 20 using PhSO(2)CH(2)CH(2)OTf is possible despite the presence of potentially nucleophilic aziridine nitrogen. The resulting oxazolium salt 22 reacts with BnNMe(3)(+)CN(-) to produce the azomethine ylide 24b via electrocyclic ring opening of an oxazoline

A convenient and practical synthesis of imidazol-1-yl-acetic acid hydrochloride was achieved via N-alkylation of imidazole using tert-butyl chloroacetate followed by a non-aqueous ester cleavage of the resulting imidazol-1-yl-acetic acid tert-butyl ester in the presence of titanium tetrachloride. The synthesized imidazol-1-yl-acetic
