The development of a visible light promoted, mild and greener approach for the synthesis of highly functionalized thiazoles and imidazo[2, 1-b]thiazoles under photochemical activation in EtOH:H2O green medium is demonstrated....
Several straightforward and practical processes have been established for the construction of 2-aminothiazoles, 1,3-thiazoles and 1,3-selenazoles from aryliodoazides. These strategies successfully proceed with a wide spectrum of substituted thioamides and its derivatives producing the resulting five-membered heterocycles obtained in satisfactory yields. The unique features of these protocols are operational
