چکیده
|
Egg shell has been utilized as a natural, green, reusable and eco-friendly reagent for the synthesis of spiro[4h-pyran-oxindole] derivatives by one-pot multicomponent reaction of isatins, 1,3-diketones, and malononitrile/ ethyl cyanoacetate. good functional group tolerance and broad scope of usable substrates are other prominent features of the present methodology.
