Abstract
Dimethyl acetylendicarboxylate reacts with phenacylanilines to give Michael adducts, which undergo cyclization to pyrrole derivatives. Similarly, ethyl anthranilate and aniline react with dimethyl acetylenedicarboxylate giving rise to the corresponding fumarates which undergo cyclization under pyrolytic conditions to give 8-carbethoxy-2-carbomethoxy-4(1H)-quinolone and α-anilino-N-phenyl-maleimide, respectively.
