A novel and efficient reaction has been developed to synthesize a set of substituted 2-aminothiazoles from α-nitroepoxides and ammonium thiocyanate. This reaction could proceed smoothly at mild condition, to afford products for a wide range of substrates with good to excellent yields. A possible mechanism has also been proposed.
An efficient synthesis of 2,4,5-trisubstituted thiazoles via the reaction of α-nitroepoxides and thioureas under mild conditions has been developed. This reaction proceeded well at room temperature, to afford products in excellent yields for a wide range of substrate, and a possible mechanism has also been proposed.
