Eco-friendly synthesis of 2-aminothiazoles using Nafion-H as a recyclable catalyst in PEG–water solvent system

Abstract

A simple, efficient, single step and environmentally benign synthesis of 2-aminothiazoles is described in this paper. This green protocol was catalyzed by recyclable solid supported Nafion-H using polyethylene glycol–water solvent system with improved efficiency and reduced waste production.

Keywords:
