is prepared from cyclododecanone via four steps: ethoxycarbonylation, condensation with 1,4-dibromobutane, saponification, and decarboxylation. Photolysis of the bicyclic ketone yields a ketene which is trapped with methanol to afford methyl cyclopentadecanecarboxylate or alternatively oxidized to exaltone directly. The ester is also converted into exaltone via five steps. dl-Muscone is prepared by
双环[9•4•1]十六烷-16-酮是由环十二酮通过乙氧基羰基化、与1,4-二溴丁烷缩合、皂化和脱羧四个步骤制备的。双环酮的光解产生乙烯酮,该乙烯酮被甲醇捕获以提供环十五烷羧酸甲酯或直接氧化为 exaltone。该酯也通过五个步骤转化为 exaltone。dl-Muscone 是通过以 14-甲基双环-[10•3•1]十六烷-16-one 作为关键中间体对环十三烷酮应用相同的方案制备的。
