A new method for the synthesis of dihydroimidazo[1,2-a][1,3,5]triazin-4(6H)-ones via copper(I)-catalyzed hydroamination was developed. In addition, for the first time, iodoalkynes were shown to participate in the copper(I)-catalyzed intramolecular hydroamination reaction with exclusive formation of E-isomers.
开发了一种通过铜(I) 催化加氢胺化合成二氢咪唑并[1,2- a ][1,3,5]triazin-4(6 H )-ones 的新方法。此外,碘炔烃首次被证明参与了铜(I)催化的分子内加氢胺化反应,并形成了E-异构体。
