One-Pot Synthesis of Enaminones Using Gold's Reagent

Enaminones were efficiently prepared via modification for Gupton method, which depends on carrying out the latter procedure in one step reaction, avoiding the isolation of [3-(dimethylamino)-2-azaprop-2-en-1- ylidene]dimethylammonium chloride (Gold's reagent) (5) which is prepared in situ from cyanuric chloride (4) then it reacts successfully with ketone 1a-j to produce the enaminones 3a-j in suitable yields. The modified method overcomes the drawbacks of the known methods for preparation of enaminones.
