Aw. Erian et al., POLYFUNCTIONALLY SUBSTITUTED HETEROCYCLES - SYNTHESIS OF NEW POLYFUNCTIONALLY SUBSTITUTED PHTHALAZINES, PYRIDO[3,4-C]PYRIDAZINES AND PYRAZOLO[3,4-C]PYRIDAZINES, Phosphorus, sulfur and silicon and the related elements, 122, 1997, pp. 133-141
Several new alkylpyridine and pyridazine derivatives have been synthes
ized. The reactivity of these alkylazines towards aromatic aldehydes a
nd sulphur are reported. New syntheses of pyrido[3,4-C]pyridines and p
hthalazines were achieved.
