1H-indole-3-carbaldehyde with various CH acids gave a number of substituted 3-(1H-indol-3-yl)acrylonitriles and acrylamides which were alkylated to afford the corresponding N-alkyl derivatives. The latter were used as Michael acceptors in the synthesis of 4H-pyran, pyridine, 5,6,7,8-tetrahydroquinoline, and [1,3]thiazolo[3,2-a]pyridine derivatives containing an indole fragment.

Sequential reaction of indole-3-carbaldehyde with cyanothioacetamide and KOH led to the formation of potassium 6-amino-4-(1H-indol-3-yl)-3,5-dicyanopyridine-2-thiolate. S-Alkylation of the latter afforded new functional derivatives of 3-(pyridine-4-yl)-1H-indole and 4-(1H-indol-3-yl)-thieno[2,3-b]pyridine.
