Herein, we report the synthesis of six‐membered P,O‐heterocycles from dialkynylphosphine oxides. By using gold(I) complexes, the chemoselectivity of the reaction was switched from literature‐reported double hydration to a hydration/intramolecular cyclization cascade. Control experiments indicated that the first alkyne hydration product is an intermediate of the reaction. In addition, a density functional
本文中,我们报道了由二炔基膦氧化物合成六元P,O-杂环。通过使用金(I)配合物,反应的化学选择性从文献报道的双重水合转变为水合/分子内环化级联反应。对照实验表明,第一炔烃水合产物是反应的中间体。此外,密度泛函理论(DFT)计算允许合理化所观察到的化学选择性。
