We report the heteroannulations of bicyclobutane derivatives bearing enol ether groups in the presence of H2O under mild conditions. The reaction affords spirocyclobutanes with cyclic acetal groups via the Au-catalyzed hydration of the enol ether group and subsequent intramolecular cyclization.
我们报告了在温和条件下存在 H 2 O 的情况下带有烯醇醚基团的双环丁烷衍生物的杂环化。该反应通过烯醇醚基的 Au 催化水合和随后的分子内环化反应得到具有环状缩醛基团的螺环丁烷。
