Abstract
The present invention relates to a process of manufacturing (6R,10R)-6,10,14-trimethylpentadecan-2-one in a multistep synthesis from a mixture of (5E,9E)-, (5E,9Z)-, (5Z,9E)- and (5Z.9Z)-isomers of 6,10,14-trimethylpentadeca-5,9,13-trien-2-one or 6,10,14-trimethylpentadeca-5,9-dien-2-one. The process is very advantageous in that it forms in an efficient way the desired chiral product from a mixture of stereoisomers of the starting product.
