Abstract
Official abstract text for this publication.
The present invention relates to a process of manufacturing compound having stereogenic centers from a mixture of E/Z isomers of unsaturated compounds having prochiral double bonds. The hydrogenation product has a specific desired configuration at the stereogenic centers. The process involves two asymmetric hydrogenation steps. The process is very advantageous in that it forms the desired chiral product from a mixture of stereoisomers of the starting product in an efficient way.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process of manufacturing a compound of formula (I-A) or (I-B) or an acetal or a ketal thereof from a mixture of E/Z isomers of compound of formula (I) or (II) or an acetal or a ketal thereof: wherein Q stands for H or CH 3 and m and p stand independently from each other for a value of 0 to 3 with the proviso that the sum of m and p is 0 to 3, and…
