has been developed, which provides an efficient way to synthesize N-aryl enaminones with a broad substrate scope and excellent functional group compatibility. The N-aryl enaminones could be converted into a series of highly valuable buildingblocks and bioactive compounds. Notably, in comparison with traditional methods, this alternative approach provides accesses to N-aryl enaminones bearing multiple

A simple, efficient, and environmentally friendly one-pot, three-component synthesis of beta-enaminones via Sonogashira coupling-Michael addition sequences under solvent-free conditions has been reported. Also the synthesis of beta-enaminones has been achieved in high yields by the direct reaction of amines with ynones under solvent-free conditions.

About specifics: A method for the regiospecific synthesis of the title compounds through an unprecedented Michael addition/deacylative diazo transfer/cyclization sequence has been established. The simple and practical method can be used for the modification of primary amines including chiral α‐amines. The process involves the formation three covalent bonds and the cleavage of two covalent bonds (see
