Described is the development of a highly efficient 2π disrotatory ring‐opening aromatization sequence using bicyclo[3.1.0]hexan‐2‐ones. This unprecedented transformation efficiently proceeds under thermal conditions and allows facile construction of uniquely substituted and polyfunctionalized benzoates. In the presence of either amines or alcohols formation of substituted anilines or ethers, respectively,
描述了使用双环[3.1.0] hexan-2-ones开发高效2π旋转开环芳构化序列的过程。这种前所未有的转变可在热条件下有效进行,并且可以轻松构建独特取代的多官能化苯甲酸酯。在胺或醇的存在下,分别形成取代的苯胺或醚。此外,该方法的实用性在短的癸二酸甲酯的合成中得到了证明。
