Highly regioselective synthesis of cis-β-enaminones by 1,4-addition of propiolaldehydes

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.

PROCESS FOR PRODUCING AN AMINOPROPYNE OR ENAMINONE

There is provided a process for producing an aminopropyne or an enaminone comprising the step of reacting a metal acetylide, an amine and a carbonyl-containing compound in the presence of a transition metal catalyst. There is also provided a process for producing an aminopropyne comprising the step of reacting a metal acetylide, an amine and a halide-containing compound in the presence of a transition metal catalyst at a reaction temperature of 50°C to 150°C. There are also provided processes to further synthesize the aminopropyne produced to obtain a butyneamine, another aminopropyne or a triazol.

Acetylide Ion (C22-) as a synthon to link electrophiles and nucleophiles: A simple method for enaminone synthesis

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.
