Syntheses of biologically active 1-(substituted aminomethyl)- 3-(2′-naphthoxyacetylhydrazono)indolin-2-ones

Havaldar, Freddy H.,Vasaikar, Pravin K.

, p. 6677 - 6680 (2012/06/18)

2-Naphthoxyacetic acid hydrazide (1) was condensed with indole- 2,3-dione in ethanol to yield 3-(2′-naphthoxyacetylhydrazono)indolin- 2-one (2) which on aminomethylation with formaldehyde and different amines furnished 1-(substituted aminomethyl)-3-(2′-naphthoxyacetyl hydrazono)indolin-2- ones. The structures of the newly synthesized compounds have been established by analytical and spectral methods. These compounds have shown promising biological activity.
