Abstract
Egg shell has been utilized as a natural, green, reusable and ecofriendly reagent for the synthesis of spiro[4H-pyran-oxindole] derivatives by onepot 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.
