An efficient, safe, and environmentally friendly tertiary butyl hydrogen peroxide (TBHP)-mediated rearrangement of aryl/alkylidene malononitrile with anilines has been developed with in situ generation of HCN as the cyanide source for the synthesis of substituted α-aminonitriles and α-aminoamide. A diverse set of α-aminonitriles and α-aminoamides was efficiently synthesized in good to excellent yields
已经开发出一种高效,安全,环保的叔丁基过氧化氢(TBHP)介导的芳基/亚烷基丙二腈与苯胺的重排反应,并原位生成HCN作为氰化物来源,用于合成取代的α-氨基腈和α-氨基酰胺。有效地合成了多种多样的α-氨基腈和α-氨基酰胺,收率很高。该方法具有广泛的底物范围和良好的官能团耐受性,并且原位生成的HCN无需使用外部氰化物源。
