readily available aldehydes, primary amines and 4-alkyl-1,4-dihydropyridines (alkyl-DHPs) for the synthesis of secondary amines at room temperature under visible light irradiation has been accomplished. This transformation occurs smoothly under mild conditions to enable facile access to various secondary amines with high efficiency, wide substrate scope and good functional group tolerance, and can be
已经完成了一种容易获得的醛、伯胺和 4-烷基-1,4-二氢吡啶 (烷基-DHP) 的无光催化剂和无过渡金属多组分反应,用于在室温下在可见光照射下合成仲胺。这种转化在温和的条件下顺利进行,可以轻松获得各种仲胺,具有高效率、宽底物范围和良好的官能团耐受性,并且易于放大。溶剂的选择对反应结果有很大影响,而 CHCl 3被证明是最佳的。此外,该良性协议的合成效用通过其在医学相关复杂分子的后期功能化中的应用得到进一步展示。
