Abstract

The present invention relates to a process of preparing tocotrienol quinones. It has been found that this process allows the formation of the R-isomer in a high yield in a very efficient and economically interesting way. Said process is particularly useful when implemented in an industrial process. Furthermore, it has been found that this process allows using isomer mixtures as they result from traditional industrial synthesis.
