A new protocol has been developed to synthesize N1-vinyl benzotriazoles from 1-arylmethylbenzotriazoles by treatment with arylaldehydes and LiN(SiMe3)2. The reaction proceeded smoothly in the absence of transition metals, showing excellent Z selectivity and broad substrate scope with good functional group tolerance.
开发了一种新方案,通过用芳醛和LiN(SiMe 3 ) 2处理从1-芳基甲基苯并三唑合成N 1 -乙烯基苯并三唑。该反应在没有过渡金属的情况下顺利进行,表现出优异的Z选择性和广泛的底物范围以及良好的官能团耐受性。
