Abstract

Synthesis of 2-cyano-N-((2-methoxynaphthalen-1-yl)methylene)- acetohydrazide (3) and its use as a key intermediate for the synthesis of some new heterocyclic compounds such as dihydropyridines (4, 6 and 8), pyrazoles (9 and 10), chromene (11), pyrroles (12 and 13), thiazoles (14 and 17) and thiophene (18-20) derivatives were described. The structures of newly synthesized compounds have been established on the basis of their IR, 1H-NMR, 13C-NMR and mass spectral data and have been screened for their antimicrobial activity.
