The present invention provides a novel macrocyclic compound exhibiting superior odor qualities and having a musk-like aroma, a method for producing the same, and a novel flavor or fragrance composition, and food products or beverages, fragrances or cosmetics, daily necessities or household goods and oral products using the novel macrocyclic compound. The invention relates to a compound represented by the formula (1), wherein each of wavy lines represents at least one of an E-configuration of C&#x2550;C double bond and an Z-configuration of C&#x2550;C double bond; m represents an integer of 0 to 10; and n represents an integer of 1 to 11, and n represents an integer of 1 to 11 when m is 0 to 4 or 6 to 10, and n is an integer of 1 or 3 to 11 when m is 5. 

Macrocyclic triene lactones having unconjugated triene structure, its production method and its synthetic intermediate

The present invention provides a method for producing sulfur-containing carboxylic acid esters that are useful for aromatizing and flavoring purpose and can cater to the needs for diversified aromatized and/or flavored products, and to further provide a fragrance and/or flavor composition comprising the ester producible by the method and an aromatized and/or flavored product comprising the same. The sulfur-containing carboxylic acid ester is represented by the following formula (3): wherein Rrepresents an alkyl group having 1 to 10 carbon atoms or an optionally substituted phenyl group (wherein the substituent thereof is an alkyl group having 1 to 4 carbon atoms or an alkoxy group having 1 to 4 carbon atoms), Rand Rindependently represent a hydrogen atom, an alkyl group having 1 to 10 carbon atoms or an alkenyl group having 2 to 10 carbon atoms, or Rand Rtogether form an alkylene group, and Rrepresents an alkyl group having 1 to 4 carbon atoms.
