A novel methodology for the synthesis of substituted isoquinolines via a nickel(0)-catalyzed [2+2+2] cycloaddition of 3,4-pyridynes with two molecules of alkyne has been established. In this reaction, it was found that 2-butyn-1,4-diol derivatives and 1,3-diynes are suitable as substrates and that a propargylic oxygen functionality in alkynes is essential for the reactivity and the selectivity of the
已经建立了一种通过镍 (0) 催化的 3,4-吡啶与两分子炔烃的 [2+2+2] 环加成合成取代异喹啉的新方法。在该反应中,发现 2-butyn-1,4-diol 衍生物和 1,3-diynes 适合作为底物,并且炔烃中的炔丙基氧官能团对于产物的反应性和选择性至关重要。
