Synthesis of 4,6-disubstituted 2-thioxo-1,2-dihydropyridine-3-carbonitriles by the reaction of acetylenic ketones with cyanothioacetamide

Synthesis of 4,6-disubstituted 2-thioxo-1,2-dihydropyridine-3-carbonitriles by the reaction of acetylenic ketones with cyanothioacetamide

The reaction of acetylenic ketones with cyanothioacetamide in the presence of morpholine yields 4,6-disubstituted 2-thioxo-1,2-dihydropyridine-3-carbonitriles. Structure of the obtained compounds was proved using 2D NMR spectroscopy, as well as transformations into 3-aminothieno[2,3-b]pyridine-2-car...
