An efficient method for the synthesis of substituted 1(2H)‐isoquinolone derivatives via nickel‐catalyzed annulation of substituted 2‐halobenzamidines with aryl alkynes in the presence of water is described. Benzo[4,5]imidazo[2,1‐a]isoquinolines were formed as the dominated products when dry dimethyl sulfoxide was used as the solvent. Furthermore, when benzyl substituted amidines were used as the substrates
描述了一种在水存在下,通过镍催化的芳基炔烃与取代的2-卤代苯甲an的环合反应,合成取代的1(2 H)-异喹诺酮衍生物的有效方法。苯并[4,5]咪唑并[2,1-一个当干二甲亚砜作为溶剂]异喹啉被形成为主导的产品。此外,当使用苄基取代的idine作为底物时,发生脱苄基反应以提供各种1-氨基异喹啉产物。
