Acetylene has been underexploited despite being a highly valuable feedstock for chemical synthesis. We have developed the first true gold(I)-catalyzed intermolecular three-component reaction between acetylene, alkenes, and alcohols to afford β-vinyl hemiaminal scaffolds from N-vinyl amides. Unusual biscyclopropyl and 3-vinyl N-heterocyclic scaffolds were obtained through the incorporation of a second
尽管乙炔是一种非常有价值的化学合成原料,但仍未得到充分利用。我们开发了第一个真金(I)催化的乙炔、烯烃和醇之间的分子间三组分反应,从N-乙烯基酰胺提供 β-乙烯基半缩醛胺支架。通过将第二个N-乙烯基单元或束缚烯烃掺入起始材料中,获得了不寻常的双环丙基和3-乙烯基N-杂环支架。
