The title compounds were obtained from reaction of variously substituted 2(1H)pyrazinones with acetylenic derivatives.Experimental evidence points out to a two step mechanism: a Diels Alder cycloaddition followed by immediate decomposition of the adducts
DIELS-ALDER REACTIONS OF THE HETERODIENE SYSTEM IN 2(1H)-PYRAZINONES
Tutonda, M.,Vanderzande, D.,Vekemans, J.,Toppet, S.,Hoornaert, G.
, p. 2509 - 2512 (2007/10/02)
Variously substituted 2(1H)-pyrazinones react with acetylenic derivatives to give specifically substituted pyridones or pyridines.The observed selectivity can be explained in terms of HO-LU interactions for the reagents and two competitive retro Diels-Ald
