Synthesis of Optically Active 2,3-Disubstituted Indoline Derivatives through Cycloaddition Reactions between Benzynes and α,β-Unsaturated γ-Aminobutyronitriles
We report a method for synthesizing opticallyactive 2,3-disubstituted indolines by the cycloaddition reaction of benzynes with various 4-[(4-toluenesulfonyl)amino]-( E )-but-2-enenitriles, which are readily prepared from the corresponding l -amino acid derivatives.
我们报告了一种通过苄与各种 4-[(4-甲苯磺酰基)氨基]-( E )-but-2-enenitriles 的环加成反应合成光学活性 2,3-二取代二氢吲哚的方法,这些化合物很容易从相应的l-氨基酸衍生物。
