The direct α-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.
                                    已开发出使用TMSCN直接对异靛酮进行α-
氰胺化反应,该反应在无催化剂的情况下在
甲醇中进行。一种新的基于
奎宁生物碱的双功能
磷酰胺催化剂7能够促进源自异靛酮的酮
亚胺与TMSCN的斯特雷克反应,最高可达74%的对映体过剩。
