Abstract

Chalcone derivatives containing a thiophene ring were prepared by the condensation of 1-(thiophen-3-yl)ethanone with aromatic aldehydes in excellent yields. The Michael addition of ethyl acetoacetate 4 to chalcone derivatives resulted in the formation of nine novel ethyl 6-aryl-4-(3-thienyl)cyclohex-3-en-2-one-1-carboxylate derivatives .
