Reaction of enaminodimidones with x-cyanocinnamonitriles and their ester analogues

ABSTRACT

The reaction of several N-Substituted enaminodimidones with alpha, B-unsaturated nitriles is described. N-Aryl-enaminodimidones were found to react differently from their N-alkyl analogues giving the quinoline B-enaminotriles [3 a-m] and their esters with the former and the arylideneamine [4 a,b] in case of the latters. Likewise, the reaction products were found to be depending on polarity and temperature. 1[H] nmr, ir and microanalysis were consistent with the chemical structure of the products
