ipso-cyclization to furnish spiro[4.5]decadienones, which rearranged to benzoxepanes upon thermal activation. The stereochemical information was relayed through this high-yielding sequence. Mechanistically, the rearrangement was proposed to proceed via the uncommon ring closure of enoate/quinone oxonium zwitterionic intermediate. Computational studies were conducted to help explain the product distribution
芳基环氧化物经历酸介导的脱芳香原环化以提供螺[4.5]癸二烯酮,其在热活化后重排为苯并氧杂环己烷。立体化学信息通过这种高产序列传递。从机理上讲,重排被认为是通过烯酸/醌氧鎓两性离子中间体不常见的闭环进行的。进行计算研究以帮助解释产物分布和非对映选择性。
