NITROGEN MONOXIDE AS CIS/TRANS ISOMERIZATION CATALYSTS FOR UNSATURATED COMPOUNDS

Номер: CN104884415A
Автор: STEMMLER RENE TOBIAS, GREINER NADINE, WILDERMANN ANGELA
Принадлежит:

The present invention relates to a process of a cis/trans isomerization of an unsaturated compound A being selected from the group consisting of unsaturated ketones, unsaturated ketals, unsaturated aldehydes, unsaturated acetals, unsaturated carboxylic acids, esters of an unsaturated carboxylic acid and amides of an unsaturated carboxylic acid using nitrogen monoxide as cis/trans isomerization catalyst. It has been observed that the isomerization is very efficient and fast.

Using mixtures of E/Z isomers to obtain quantitatively specific products by combined asymmetric hydrogenations

Номер: CN104918909A
Автор: BONRATH WERNER, MEDLOCK JONATHAN ALAN, STEMMLER RENE TOBIAS, VERZIJL GERARDUS KAREL MARIA, VRIES DE ANDREAS HENDRIKUS MARIA, NETSCHER THOMAS
Принадлежит:

The present invention relates to a process of manufacturing compound having stereogenic centres 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 centres. 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.
