One-pot condensations of formaldehyde with CH acids and enamines afforded new 4-unsubstituted derivatives of 2-oxo(thioxo)-1,2-dihydropyridine-3-carbonitrile, 2-oxo(thioxo)-1,2-dihydropyridine-3-carboxamide, ethyl 2-oxo(thioxo)-1,2-dihydropyridine-3-carboxylate, and 2-thioxo-1,2,5,6,7,8-hexahydroquinoline-3- carbonitrile, which were subjected to alkylation. © 2015 Pleiades Publishing, Ltd.

Alkylation of isopropylidene- and cyclohexylidenepropanedinitrile with phenacyl bromides gave 2,2-bis(2-aryl-2-oxoethyl)propanedinitriles. Direct alkylation of propanedinitrile with phenacyl bromides afforded only 2-(2-aryl-2-oxoethyl)propanedinitriles. © 2015 Pleiades Publishing, Ltd.

Functionally substituted partially hydrogenated thiazolo[3,2-a]quinoline and thiazolo[3,2-a]-pyridine were synthesized by multicomponent condensation of aromatic aldehydes, cyanothioacetamide, 1,3-dicarbonyl compounds, 1,2-dibromoethane, and morpholine. © 2015 Pleiades Publishing, Ltd.
