Abstract

The innovation of facile, efficient and mild procedures utilizing contemptible, conveniently separable and reusablesolid catalysts that overcome obstacles are invariably in demand. Hence, a straightforward one-pot multicomponent reaction (MCR) and an expedient procedure for the synthesis of pyran annulated heterocycles 5 a�k and 6 l�v is developed using Chitosan-Zinc oxide (CS-ZnO) hybrid nanocatalyst. Use of aqueous medium is one of the major highlight of the present protocol. This protocol renders ease of operation, facile work up and magnified yields (90�95 ) as well as explores the use of modified polymeric substrates in the organic synthesis. © 2022 Wiley-VCH GmbH.
