Abstract:
Nano Ag/kaolin has been used as an effective heterogeneous catalyst for one-pot synthesis of spiro[4H-pyran-3,3'-oxindoles] via reaction of isatin derivatives, malononitrile and cyclic 1,3-diketones under mild reaction conditions in excellent yields.
Keywords:Spirooxindoles; Heterogeneous catalyst; Cyclic 1;3-diketone; Nano Ag/kaolin; Malononitrile
