已经开发出使用 TMSCN 直接对靛红进行 α-氰胺化,该方法在甲醇中进行,无需任何催化剂。一种新型双功能金鸡纳生物碱基膦酰胺催化剂 7 可以促进靛红衍生的酮亚胺与 TMSCN 的 Strecker 反应,EE 高达 74%。
The direct alpha-cyanoamination of isatins using TMSCN has been developed, which is carried out in methanol without any catalyst. A new bifunctional cinchona alkaloid-based phosphinamide catalyst 7 could promote the Strecker reaction of isatins derived ketimine with TMSCN in up to 74% ee.
