Webscope and mechanism of the reaction. In contrast, Hajos and Parrish put forward a mechanism involving a carbinolamine that is now obsolete, since it is appreciated that the reaction proceeds through enamine catalysis, but, perhaps more importantly, the authors recognized that the proline catalyst plays the same role as an enzyme. holcombe armsWebIt doesn't matter if the proton is in a ring or not. 1° amines form the more stable imines. 2° amines form enamines. Consider the reaction of acetaldehyde with CH₃NHR, where R can be H or CH₃. The intermediate carbocation is CH₃-C⁺H—NRCH₃.
