Abstract: The present invention relates to a metal powder catalyst and its use in the selective catalytic hydrogenation of organic starting materials comprising a carbon-carbon triple bond. The powder catalyst comprises a metal alloy carrier, wherein the metal alloy comprises (i) 55 weight-% (wt-%)-80 wt-%, based on the total weight of the metal alloy, of Co, and (ii) 20 wt-%-40 wt-%, based on the total weight of the metal alloy, of Cr, and (iii) 2 wt-%-10 wt-%, based on the total weight of the metal alloy, of Mo, and wherein the said metal alloy is coated by a metal oxide layer and impregnated with Pd, and is characterized in that the metal oxide layer comprises CeO2.

Abstract: The present invention relates to a process of manufacturing (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 forms in an efficient way the desired chiral product from a mixture of stereoisomers of the starting product.

Abstract: The present invention relates to a synthesis of chromanones or chromanes in a stereospecific matter in view of the 2-position in the chromanone or chromane ring. It has been found that this synthesis is particularly possible in the presence of a chiral compound of a specific type and of at least one Bransted acid or in the presence a specific chiral compound having a Bransted acid functional group in the molecule.
