A rhodium-catalyzed enantioselective click cycloaddition of azides and alkynes for rapid and modular access to atropisomeric triazoles is reported. This click process features very mild reaction conditions, superior efficiency and enantioselectivity, broad substrate scope and facile scalability. The racemization study and further derivatizations demonstrate the good configurational stability of the
报道了一种铑催化的叠氮化物和炔烃的对映选择性点击环加成,用于快速和模块化地获得阻转异构三唑。这种点击过程具有非常温和的反应条件、卓越的效率和对映选择性、广泛的底物范围和易于扩展的特点。外消旋研究和进一步的衍生化证明了所获得的轴向手性三唑产物具有良好的构型稳定性。
