SYNTHESIS AND PROPERTIES OF HYDROGENATED 2-ALKYLTHIO-5-OXO-3-CYANOINDENO-PYRIDINES

Krauze, A. A.,Liepin'sh, E. E.,Dubur, G. Ya.

, p. 99 - 103 (1990)

Condensation of 2-arylidene-1,3-indandiones with cyanothioacetamide in the presence of piperidine, followed by treatment with alkyl halides, has given partially hydrogenated 2-alkylthio-5-oxoindeno-pyridines, the oxidation, interconversion, and Thorpe cyclization of which to give a novel heterocyclic system, indenopyridothiophene, have been examined.
