Microwave Promoted Environmentally Benign Synthesis of 2-Aminobenzothiazoles and Their Urea Derivatives
摘要:
2-Aminobenzothiazoles were efficiently synthesized using stable, crystalline tetrabutylammonium tribromide instead of toxic, corrosive liquid bromine under solvent-free and microwave irradiation condition. Furthermore, benzothiazol-2-ylureas were synthesized in good to high yield by reactions of 2-aminobenzothiazoles with N-trichloroacetanilides, which were used as a substitute for toxic, unstable isocyanates, under microwave irradiation condition. This protocol has advantages of no utilization of hazardous chemicals, rapid reaction rate, high yield, and easy work-up procedure.

vital roles in cancercell proliferation, tumor inflammation, and angiogenesis, making them attractive drug targets. In clear cell renal cell carcinoma (RCC) and head and neck squamous cell carcinoma (HNSCC), where CXCR1/2 is overexpressed, inhibition studies are limited. Building upon previous research efforts, we investigated new N,N′-diarylurea analogues as ELR+CXCL-CXCR1/2 inhibitors. Evaluations
