Title:

METHOD FOR PRODUCING 3-METHYLCYCLOPENTADECANES AND INTERMEDIATE FOR PRODUCING 3-METHYLCYCLOPENTADECANES

Document Type and Number:

Japanese Patent JP2009102244

Kind Code:

A

Abstract:

To provide a method for producing a 3-methyl-cyclopentadecane.

A 9-methyl-1,16-heptadecadiene represented by the general formula [I] (wherein X1 and X2 are each CH-OH, CH-OAc (Ac is an acetyl group) or C=O) is reacted in the presence of a metathesis reaction catalyst to give a 3-methyl-10-cyclopentadecene represented by the general formula [II] (wherein X1 and X2 are each as shown above; and wavy line is cis- or trans-structural isomer), which is then subjected to hydrogenation reaction to give a 3-methylcyclopentadecane represented by the general formula [III] (wherein X1 and X2 are each as shown above).
