摘要:
The present invention relates to a process of manufacturing (6R,10R)-6,10,14-trimetylpentadecan-2-one in a multistep synthesis from 3,7-dimetyloct-2-enal or 3,7-dimetylocta-2,6-dienal. 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.
摘要:
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.
