Abstract

Synthesis of arylpropynamides and their reactions with different malonic acid derivatives is described. Treatment of arylpropynamides with unsubstituted malonyl chloride furnished N-(3-arylprop-2-ynoyl)-6-chloro-4-hydroxy-2-oxo-2H-pyran-3-carboxamides; monosubstituted malonyl chlorides or their derivatives, (chlorocarbonyl)ethylketenes, reacted with arylpropynamides to give 4-hydroxy-2-(phenylethynyl)-6H-1,3-oxazin-6-ones; and the reaction of arylpropynamides with disubstituted malonyl chlorides furnished open-chain arylpropenamides exclusively.
