Substituted 4-[(3-cyanopyridin-2-yl)thiomethyl]coumarins have been synthesized by the alkylation of 2-mercapto-4,6-dimethylnicotinonitrile with 4-chloromethylcoumarins. Substituted 4-(3-amino-thieno[2,3-b]pyridin-2-yl) coumarins have been obtained by a subsequent intramolecular condensation of the methylene and cyano groups. 6H-Chromeno[4,3-d]thieno[3,2-b:5,4-b']dipyridin-6- ones were isolated as a result of the interaction of these compounds with aldehydes, and their aminomethyl derivatives were synthesized.
