摘要

将铜(I)介导的叠氮-炔环化反应与交叉耦合结合起来，合成了[6,5,5] 环融合的三环三唑。研究了铜(I)介导的叠氮-炔环化反应在 2-碘芳基丙炔或丙炔酮上的应用。在催化 Cu(I) 盐或铜上的 N-供体配体的情况下，只能形成叠氮-炔环化产物。然而，在等摩尔量的碘化铜（I）和三乙胺的作用下，叠氮-炔环加成反应与交叉耦合反应生成了新的[6,5,5] 环融合三环三唑。

Synthesis of [6,5,5]Ring-Fused Tricyclic Triazoles by Copper-Promoted Double Cyclization

Copper(I)-mediated azide-alkyne cycloaddition was coupled with cross-coupling for the synthesis of [6,5,5] ring-fused tricyclic triazoles. Copper(I)-mediated azide-alkyne cycloaddition was investigated on 2-iodoaryl propynes or propynones. With catalytic amount of Cu(I) salts or with N-donor ligands on copper only the products of azide-alkyne cycloadditions were formed. However, with an equimolar amount of copper(I) iodide and triethylamine new [6,5,5] ring-fused tricyclic triazoles were formed by azide-alkyne cycloadditon coupled to a cross-coupling reaction.
