Abstract

Abstract An efficient and expeditious catalyst-free protocol was developed for the construction of di-and trisubstituted thiazoles from α-haloketones and thioureas/thioamides in PEG. The reaction was carried out at ambient temperature, and the products were obtained in excellent isolated yields (91–98%). Additionally, PEG could be recovered easily and was reused without evident loss in activity.
