AbstractA direct multi-component assembling of isatin, cyclohexanone, and 2 mol of malononitrile in the presence of catalytic amount of DABCO in aq. ethanol leads to functionalized spirooxindoles at ambient temperature. The novelties of the method are multi-component route, short time duration, excellent yields of products, mild reaction conditions, easy work-up procedure, as well as isolation of product
