1-苯甲酰基-5-苯基-2-硫代缩二脲与溴代苯乙酮的成环反应研究

Study on the cycle reaction between l-benzoyl-5-phernyl-2-thiobiuret and 2-bromo-l-phenylethanone

1-苯甲酰基-5-苯基-2-硫代缩二脲与溴代苯乙酮在弱碱性条件生成了1-苯甲酰胺基-4-苯基噻唑.产物结构经红外光谱、核磁共振光谱、质谱分析得到了证实.

l-benzoyl-5-phenyl-2-thiobiuret was reacted with 2-bromo-1-phenylethan one under the weak basic condition to afford the N-(4-phenylthiazole-2-yl) benz-amide. The structure of product was characterized by IR,1H NMR,13C NMR,MS spectra.
