Synthesis of Some New Spiropyrans containing indoline moiety

Research Abstract

3-dicyanomethylidine-2-oxoindolines 1a-c reacted with different cyclic carbonyl compounds to afford new spiroheterocyclic derivatives 2a-c to 5a-c which are analogues of some reported biologically active spiropolycyclic compounds.

Efficient Synthesis of Some New Spirochromens containing indoline moiety

Research Abstract

2-Naphthol reacted with 3-dicyanomethylidine-1-ethyl-2-oxoindoline in absolute ethanol to afford 2-Amino-3-cyano-1'-ethylspiro{benzo[f]chromen-4,3'-indolin}-2'-one, which used as key intermediate to synthesis fused spiropolyheterocyclic derivatives of pyrimido- benzochromen and/or pyridobenzochromen nucleus incorporated indoline moiety.
