synthesis of substituted hemiaminal via addition of ethers to quinone imine ketals (QIKs) has been developed under metal-free conditions. In the presence of tetrabutylammonium chloride and potassium persulfate (K2S2O8), QIKs couple efficiently with cyclic and acyclic ethers to give hemiaminals. This strategy offers an easy access to substituted hemiaminal ethers with high functional group tolerance in good
通过在无金属条件下开发通过将醚添加到醌亚胺缩酮(QIKs)的高度区域选择性合成取代的烟酰胺的方法。在氯化四丁基铵和过硫酸钾(K 2 S 2 O 8)的存在下,QIK与环状和非环状醚有效偶联,得到缩醛。此策略可轻松获得具有高官能团耐受性且产率高至优异的取代的人类薄荷醚。
