efficient methodology has been developed for the synthesis of 1,4,5-trisubstituted dicarbonyl 1,2,3-triazoles and 1,4-disubstituted sole-carbonyl 1,2,3-triazoles via a C–C bond cleavage process. The Regitz diazo transfer and C–C bond cleavage were the key steps of this transformation, which provided diverse carbonyl-substituted structural 1,2,3-triazoles. This reaction featured with excellent regioselectivity
已经开发了一种直接有效的方法,可通过CC键断裂合成1,4,5-三取代的二羰基1,2,3-三唑和1,4-二取代的唯一羰基1,2,3-三唑过程。Regitz重氮转移和CC键断裂是该转化的关键步骤,它提供了各种羰基取代的结构1,2,3-三唑。该反应具有出色的区域选择性,宽泛的官能团耐受性和温和条件。
