摘要
An new overall lower energy pathway for the amine-catalyzed Morita-Baylis-Hillman reaction is proposed from computations at the M06-2X/6-311++G(d,p) level of theory. The pathway involves proton-transfer from the ammonium ion to the alkoxide formed from the aldol reaction through a seven-membered ring transition state structure followed by highly exothermic Hofmann elimination through a five-membered ring transition state structure to form the product and also release the catalyst to carry on with the process all over again.
