ABSTRACT:
Among the compounds represented by the general formula (1),(in the formula, n is an integer of 7 to 13)in particular, 11-methyl-13-tridecanolide of which n=8, 12-methyl-14-tetradecanolide of which n=9, and 13-methyl-15-pentadecanolide of which n=10 are novel compounds which have not been reported in prior art and the evaluation of the compounds for fragrance characteristics revealed that the compounds are macrocyclic lactone musks having not only strong fragrance of musk excellent in persistency but also fragrance characteristics like nitro musks. Furthermore, in the present invention, by containing at least one of those novel compounds, perfume compositions or perfume products having distinctive fragrance characteristics are obtained. The invention also provides a novel process for the production of compounds represented by the general formula (1).
