Abstract
Ethyl 2-[5-aryl-2-oxofuran-3(2H)-ylideneamino]-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylates reacted with secondary amines to give 4-aryl-2-(thiophen-2-yl)-4-oxobutanamides, whereas their reaction with piperazine afforded N,N′-disubstituted piperazine derivatives regardless of the reactant ratio.
