A facile regiospecific synthesis of 2,3-disubstituted indoles from isatins has been developed. Nucleophilic addition of Grignard reagents to commercially available isatins, followed by reduction with borane, afforded an array of structurally diverse 2,3-disubstituted indoles in moderate to good yields. The method described herein represents a novel and very simple approach to synthesize various 2,3-disubstituted
已经开发了从靛红容易地区域特异性合成2,3-二取代的吲哚的方法。将格氏试剂亲核地添加到市售的靛红中,然后用硼烷还原,以中等至良好的产率提供了结构上不同的2,3-二取代的吲哚阵列。本文所述的方法代表了一种新颖且非常简单的方法,用于合成各种2,3-二取代的吲哚,这是制药工业和药物化学中极为重要的结构基序。
