A double Sonogashira-type coupling reaction between aryl bromides and alkynes using a catalytic Pd/XPhos (2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl) system was introduced as an efficient method for the synthesis of shape-persistent macrocycles (SPMs). This approach is advantageous in the synthesis of SPMs with a single pyridine unit.
介绍了使用催化Pd / XPhos(2-dicyclohexylphosphino-2',4',6'-triisopropylbiphenyl)系统在芳基溴化物和炔烃之间进行的双重Sonogashira型偶联反应,作为合成形状持久大环化合物的有效方法( SPM)。该方法在具有单个吡啶单元的SPM的合成中是有利的。
