Synthesis and properties of 2-(2-oxoindolin-3-ylidene)-2-cyanoacetic acid piperidides and morpholides
- 36 Downloads
The reaction of isatins with cyanoacetic acid piperidide or morpholide gives the corresponding derivatives of 2-(2-oxoindolin-3-ylidene)-2-cyanoacetic acid, which may be reduced to give amides of 2-(2-oxoindolin-3-yl)-2-cyanoacetic acid and react with ethanolic alkali to give quinoline derivatives.
