A site-selective C-4/C-8 alkynylation of isoquinolones catalyzed by gold and rhodium complexes is reported. A broad range of synthetically useful functional groups (−F, −Cl, −Br, −CF3, −OMe, alkyl, etc.) were tolerated, providing an efficient and robust protocol for the synthesis either C-4- or C-8-alkynylated isoquinolones.
据报道,由金和铑配合物催化的异喹诺酮类化合物的位点选择性C-4 / C-8炔基化反应。宽泛的合成有用的官能团(-F,-Cl,-Br,-CF 3,-OMe,烷基等)可耐受,从而为合成C-4-或C-提供了有效而稳定的方案8-炔基异喹诺酮。
