homo- and heteroannular bicyclic β-diketones is reported. The method employs the copper acetate mediated 1,4-conjugate addition of organozinc derivatives of iodopropionate and iodobutanoate esters to α,β-unsaturated cycloalkenones, followed by intramolecular Dieckmann condensation.
报告了制备同型和杂环双环 β-二酮的通用和可重复的方法。该方法采用乙酸铜介导的碘丙酸酯和碘丁酸酯的有机锌衍生物与 α,β-不饱和环烯酮的 1,4-共轭加成,然后进行分子内 Dieckmann 缩合。
