Abstract

The present invention relates to a process of manufacturing (6R,10R)-6,10,14-trimetylpentadecan-2-one in a multistep synthesis from 6,10-dimetylundec-5-en-2-one or 6,10-dimetylundeca-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.
