Sm. Hussain et al., NEW SYNTHESIS OF POLYFUNCTIONALLY SUBSTITUTED 2-MERCAPTOPYRIDINES ANDFUSED PYRIDINES, Gazzetta chimica italiana, 124(2), 1994, pp. 97-101
Facile unequivocal syntheses of the title compounds are reported by re
acting monothiomalonamide, 1a, or its anilide analogue, 1b, with alpha
-cyanocinnamonitriles 2a-c. Chemical and spectroscopic evidences for t
he structures of the newly synthesised compounds are described.
