A new strategy for thiazoles via copper-catalyzed [3+1+1]-type condensation reaction from oximes, anhydrides and potassiumthiocyanate (KSCN) is developed herein. The transformation has good functional group tolerance and various thiazoles were formed smoothly in good to excellent yields under mild reaction conditions. This process involves copper-catalyzed N-O/C-S bond cleavages, activation of vinyl sp2 C-H bond, and C-S/C-N bond formations which are under redox-neutral conditions as well as operational simplicity.

A concise synthesis of the title compounds 6 is accomplished in high overall yield in a two step process starting from bromoketone 4. A thiazole ring formation and a non-phenolic oxidative coupling reaction using PIFA are features of the described synthesis. An exploration of the electronic requirements and the regioselectivity of the cyclization is also presented.
