Patent ID: 7479574

Claim:
A method of producing muscone represented by the following Formula (I): the method comprising: reacting 2-cyclopentadecenone represented by General Formula (III): wherein the wavy line represents a cis isomer and/or a trans isomer of double bond, with an organic metal methylation reagent via 1,4-conjugation addition reaction in the presence of a copper or nickel catalyst and an enol anion scavenger to give a 3-methyl-1-cyclopentadecene derivative represented by General Formula (II): wherein R represents a straight- or branched-chain acyl group which may have a substituent containing a heteroatom or an aromatic ring, an alkyloxycarbonyl group which may have a substituent containing a heteroatom or an aromatic ring, or a straight- or branched-chain alkyl group which may have a substituent containing a heteroatom or an aromatic ring; and the wavy line is the same as that above; and solvolyzing the enol moiety of the 3-methyl-1-cyclopentadecene derivative.
