hydrocarboxylation of 2‐alkynylanilines under very mild conditions has been developed to afford (E)‐[2‐(o‐aminophenyl)]acrylic acids, which could easily be converted to (E)‐3‐alkylidene‐2‐indolinones with important potential bioactivity. The stereoselective syntheses of two biologically active molecules, (E)‐3‐benzylidene‐2‐indolinone (chemo‐preventive potential in inducing NQO1 activity) and (E)‐3‐(3‐m
已开发出一种在非常温和的条件下用双(环辛基-1,5-二烯)镍催化2-炔基苯胺的高区域和(E)-立体选择性加氢羧化反应,以提供(E)-[2-(邻氨基苯基)]丙烯酸,很容易转化为具有重要潜在生物活性的(E)-3-亚烷基-2-吲哚满酮。两种生物活性分子的立体选择性合成,(E)-3-苄叉-2-吲哚啉酮(诱导NQO1活性的化学预防潜力)和(E)-3-(3-甲基丁叉)-2-吲哚啉酮(天然产物)举例说明了从烟叶升麻中分离出的具有对HL-60细胞的细胞毒活性的化合物。
