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

Alkylation of cyclododecanone with alpha,omega-dibromoalkanes Br(CH)(n)Br (n = 3, 4, 5) under conditions of phase-transfer catalysis in the presence of KOH results in the formation of either bicyclic ketones for n = 3 and 5 or a mixture of bicyclic and spirocyclic ketones for n = 4.
