Synthesis of new 3-substituted indole derivatives

Abstract

Treatment of 3-cyanoacetyl-2-methylindole (1) with phenyl isothiocyanate gave the corresponding thioacetanilide derivative 3. The thioacetanilide 3 was utilized as the key intermediate for the synthesis of some new 1,3,4-thiadiazole (6a, b and 9a-e), thiophene (11a, b), thiazolidin-4-one (4), thiazole (12 and 13), and benzothiazole (15) derivatives. The structures of the new compounds were elucidated on the basis of elemental analyses and spectral data. © 2010 Verlag der Zeitschrift für Naturforschung,.
