Cerium oxide-catalyzed multicomponent condensation approach to spirooxindoles in water.

Rajeev Shrestha1, Kavita Sharma1, Yong Rok Lee2, Young-Jung Wee3.   

Abstract

An efficient and facile green synthesis of spirooxindole derivatives bearing pyrano[2,3-c]pyrazole moiety has been achieved via a [Formula: see text]-NPs catalyzed four-component reaction in water. The protocol offers an environmentally benign and effective approach to highly functionalized and biologically interesting spiro[indoline-3,4[Formula: see text]-pyrano[2,3-c]pyrazole] derivatives. The synthesized compounds exhibit potent antioxidant and antibacterial activities.
