Use

Cyclopentadecanone is a musk fragrance found in the scent gland of the male civet cat. A number of syntheses have been developed for its manufacture [260]. Among these, the so-called Story procedure is the only route that has the potential to make cyclopentadecanone available on a larger scale, but due to the handling of hydroperoxides, the process is difficult to manage. The process starts from tricyclohexylidene triperoxide, which is obtained by oxidation of cyclohexanone with hydrogen peroxide. Pyrolysis leads to a mixture of 1,16-hexadecanolide and cyclopentadecane. The latter is oxidized by oxygen under boric acid catalysis to cyclopentadecanol, which is subsequently oxidized to cyclopentadecanone. Due to the availability of long-chained aliphatic dicarboxylic acids by biotechnological processes, a Dieckmann condensation reaction may also possibly be a useful route to produce this macrocyclic ketone. Cyclopentadecanone is used in fine fragrances：
