Room-temperature synthesis of 4-alkyl/aryl-2-aminothiazoles from vinyl azides and ammonium thiocyanate was accomplished with the aid of copper salts and blue LED irradiation. Mechanism investigation indicates that in situ-formed Cu(NCS)2– plays dual important roles in the reaction: (1) as the photocatalyst to activate vinyl azides, (2) as the Lewis acid catalyst to promote ring opening of 2H-azirines

A series of (2-aminothiazol-4-yl)methylester (5a–t) derivatives were synthesized in good yields and characterized by 1H NMR, 13C NMR, mass spectral and elemental analyses. The crystal structure of 5a was evidenced by X-ray diffraction study. The compounds were evaluated for their preliminary in vitro antibacterial, antifungal activity and were screened for antitubercular activity against Mycobacterium
