In the presence of Bronsted acid TfOH, methylenecyclopropanes react with nitriles to give [3+2] cycloaddition products in good to high yields along with Ritter reaction products. In many cases, [3+2] cycloaddition products are obtained as the major products. The reaction conditions have been carefully examined and the plausible mechanism has been proposed.

N-[(E)-Homocinnamyl] amides were stereoselectively synthesized by the reaction of the methylenecyclopropanes (MCPs) with nitriles under acidic conditions in moderate yields in a one-pot manner.
