A copper-catalyzed addition of arylboronates to isatins has been developed to give 3-aryl-3-hydroxy-2-oxindoles under mild conditions. The catalytic cycle of this process has been examined through a series of stoichiometric reactions and an effective asymmetric variant has also been described by the use of a chiral N-heterocyclic carbene ligand.
已经开发了铜催化将芳基硼酸酯加到靛红中,以在温和的条件下得到3-芳基-3-羟基-2-氧吲哚。已经通过一系列化学计量反应检查了该方法的催化循环,并且还通过使用手性N-杂环卡宾配体描述了有效的不对称变体。
