Abstract

A facile iodine-mediated decarboxylative cyclization from α-amino acids and N-heterocyclic carbaldehydes was developed. By virtue of this method, a series of imidazo [1, 5-a] N- heterocycles can be synthesized efficiently under mild conditions. A tentative reaction mechanism was proposed based on the experimental results and previous reports.
