general method to generate umpolung of aldimines with cyanide was developed via the addition of cyanide to aldimines followed by a proton transfer from the carbon atom to the nitrogen atom in the resulting cyanide adducts. This novel method was successfully applied to the first imino‐Stetter reaction of aldimines obtained from 2‐aminocinnamic acid derivatives and aromatic aldehydes with cyanide, affording
以生成与氰化物醛亚胺的极性转换的一般方法被开发通过加入氰化物到醛亚胺随后从碳原子的质子转移到氮原子在所得氰化物加合物。该新方法已成功应用于从2-氨基肉桂酸衍生物和芳族醛中得到的醛亚胺与氰化物的亚氨基Stetter反应,从而获得了2-芳基取代的吲哚3-乙酸衍生物。此外,通过合成FPTase抑制剂(一种生物学上重要的2-芳基吲哚-3-乙酸衍生物)成功证明了该方法的有效性。
