KAl(SO4)2.12H2O(Alum): An Efficient Catalyst for the Synthesis of Novel bis[spiro(quinazoline-oxindole)] Derivatives Via One-Pot Pseudo Five-Component Reactions

An efficient and convenient protocol for the synthesis of novel bis[spiro(quinazoline‐oxindole)] derivatives by one‐pot pseudo five‐component condensation of two molecules of isatoic anhydride, two molecules of isatins, and diamines in high yields and very short reaction time is described. This gree...

Summary:An efficient and convenient protocol for the synthesis of novel bis[spiro(quinazoline‐oxindole)] derivatives by one‐pot pseudo five‐component condensation of two molecules of isatoic anhydride, two molecules of isatins, and diamines in high yields and very short reaction time is described. This green protocol was catalyzed by Alum as a non‐toxic, reusable, inexpensive, and easily available reagent.
