Bismuth Chloride Mediated Synthesis, Antimicrobial, and Anti-Inflammatory Activities of New 4-Aryl-2-Amino Thiazoles
摘要:
Synthesis of 4-aryl-2-Amino thiazoles (3a-u), (4a-c), and (5a-c) was achieved from the reaction of 4-butyl phenacyl chlorides (2a-c) with N-substituted thioureas, in the presence of Bismuth Chloride. The antimicrobial and anti-inflammatory activities of the final products were also studied.
An efficient procedure for the synthesis of 2-aminothiazoles via DBH-mediated oxidative cyclization of styrenes and thioureas is reported. Various alkenes were successfully transformed to the corresponding 2-aminothiazoles in yields of 10–81% via a two-step one-pot manner using DBH as both the bromine source and oxidant. The method can be readily carried out in gram-scale and successfully applied to
