A convenient one-pot strategy for the regioselective synthesis of cis-β-enaminones has been developed via the condensation of propiolaldehydes and amines in EtOH. This process has opened a new synthetic route to enamines in good yield. A possible reaction mechanism involving a Michael addition/enol tautomerization via a six-membered ring transition state is proposed.

Friendly competition: A three-component reaction system composed of calcium carbide, an aryl aldehyde, and an amine gave enaminones or propargylamines (see picture) in a predictable manner through competitive pathways. The system enables the cost-efficient synthesis of a variety of enaminones from readily accessible small molecules and demonstrates the versatility of the acetylide ion, which can be used to bridge electrophiles and nucleophiles.
