, p. 1255 - 1261 (2011)
Chalcone derivatives containing thiophene ring were prepared by the condensation of 3-acetylthiophene with aromatic aldehydes in excellent yields. The addition of ethyl acetoacetate to chalcone derivatives 3a-3h in the presence of solid NaOH in CH2Cl2 resulted in the formation of the mixture of bicyclic lactone derivatives 5a-5h and 6-(ethoxycarbonyl) cyclohexenone derivatives 6a-6h.
Potassium tert-butoxide catalyzed synthesis and characterization of novel 3-aryl-3-(phenylthio)-1-(thiophen-3-yl)propan-1-one derivatives

scheme or table, p. 341 - 344 (2012/04/23)
A series of thiophenyl-containing 3-thiophene derivatives (4a-4i) were prepared via the reaction of chalcone-analogua compounds (3a-3i) and thiophenol in the presence of catalytic amount of KOBu-t in CH2Cl2 with moderate to high yiel
