(6r, 10r) -6,10,14-trimethylpentadecan-2-one prepared from 6,10,14-trimethylpentadeca-5,9,13-trien-2-one or 6,10,14-trimethylpentadeca-5 9-dien-2-one

摘要

summary (6r, 10r) -6,10,14-trimethylpentadecan-2-one prepared from 6,10,14-trimethylpentadeca-5,9,13-trien-2-one or 6,10,14-trimethylpentadeca- 5,9-dien-2-one The present invention relates to a manufacturing process of (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 efficiently forms the desired chiral product from a mixture of stereoisomers of the starting product.
