Abstract

A simple and efficient method has been developed for the synthesis of 2-aminothiazoles from α-bromo ketones in one-pot using a supported reagents system, KSCN/SiO2– RNH3OAc/Al2O3, in which α-bromo ketone reacts first with KSCN/SiO2 and the product, α- thiocyano ketone, reacts with RNH3OAc/Al2O3 to give the final product, 2-aminothiazole, in high yield.
