Synthesis of Arylamino-thieno-oxobutanamides and Reactivity Studies on the Cyclisation with the Lawesson's Reagent

Abstract: 1-aryl-2-thienyl-substituted pyrroles and 5-arylamino-2,2´-bithiophenes were synthesized by treatment of arylamino-thieno-oxobutanamides with Lawesson´s reagent. These in turn were prepared by direct amidation of 4-oxo-(2-thienyl)butanoic acid through DCC/BtOH mediated reactions.
Keywords: arylamino-thieno-oxobutanamides, Lawesson´s reagent, 1-aryl-2-(2´-thienyl)pyrroles, 5-arylamino-2,2´-bithiophenes, non-linear optical material, NLO applications.
