An expeditious, functional group-tolerant synthesis of indoles from isatins is described. Isatins are treated with Grignard reagents to yield oxindoles. These, in turn, are reduced with Schwartz’s reagent and subjected to nucleophile addition and dehydration to yield 2,3-disubstituted indoles regiospecifically. This represents a divergent approach to the synthesis of these medicinally and synthetically
描述了从靛红快速,耐官能团合成吲哚的方法。用格利雅试剂处理靛红,以生成羟吲哚。这些反过来又用Schwartz试剂还原,并进行亲核试剂加成和脱水,以区域特异性地生成2,3-二取代的吲哚。这代表了合成这些医学上和合成上重要的化合物的不同方法。
