A multicomponent reaction of cyanoselenoacetamide with aromatic aldehydes, cyclohexane-1,3-dione, and N-methylmorpholine gave N-methylmorpholinium 4-aryl-3-cyano-5-oxo-1,4,5,6,7,8-hexahydroquinoline-2-selenolates. Alkylation of the latter occurs under mild conditions with retention of the 1,4 dihydropyridine fragment to give 2-(2-R-methylseleno)-4-aryl-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carbonitriles.
