A Ni-catalyzed addition of arylboronic acids to isatins was first developed. The reaction, driven by Ni(acac)2 and dppp as the phosphine ligand, gave 3-aryl-3-hydroxy-2-oxindoles in up to 97% yield. Scopes of benzyl-protected isatins and arylboronic acids were examined. Substituted phenylboronic acids along with fused-ring and heterocyclic boronic acids reacted with isatins smoothly. Preliminary asymmetric
首先开发了Ni催化的芳基硼酸到靛红的加成反应。在Ni(acac)2和dppp作为膦配体的驱动下,该反应以高达97%的收率得到3-芳基-3-羟基-2-氧吲哚。检查了苄基保护的靛红和芳基硼酸的范围。取代的苯基硼酸与稠环和杂环硼酸一起与靛红平稳地反应。还初步研究了不对称催化,显示出中等的对映选择性。还描述了该机制。
