标 题:Formation of chiral 4-chromanones using chiral pyrrolidines in the presence of acids
发明人：MEDLOCK JONATHAN ALAN; LETINOIS ULLA; NETSCHER THOMAS; BONRATH WERNER
权利人:DSM IP ASSETS BV
摘要: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.

标题 :Process for removing certain linear isoprene trimers from a mixture of isoprene trimers
发明人：MOREL DIDIER
权利人:RHONE POULENC SANTE
摘要:A process for removing from a mixture of isoprene trimers compounds of the formula ##STR1## by reacting a mixture of cyclic and linear trimers with a compound having an activated carbon atom, of the formula: n n X--CH.sub.2 --Y n n in which one of X or Y is an electron-withdrawing group and the other is an electron-withdrawing or electron-donating group, in the presence of a catalyst consisting of a water-soluble phosphine and a rhodium compound, the reaction being carried out in water or in a water-alcohol medium, and separating the cyclic trimers and linear trimers containing the chain ##STR2## from the mixture of products of the formulae: ##STR3## which can be used, in particular, in the synthesis of vitamin E.
