Abstract
A series of dispiropyrrolidine bisoxindoles were synthesized via a multicomponent 1,3-dipolar cycloaddition reaction of isatin, sarcosine and isatylidene malononitrile in refluxing methanol. Also a series of spiropyrrolidine oxindoles and spiroindane-1,3-diones were synthesized using 2-(1H-Indole-3-carbonyl)-3-phenyl-acrylonitrile and 2-(1,3-dioxo-indan-2-ylidene)-malononitrile as dipolarophiles, respectively.
