Abstract

1. A process for the manufacture of 13-cis-retinoic acid, characterized by a) reacting 5-hydroxy-4-methyl-2(5H)-furanone with a salt of the formula see diagramm : EP0111325,P8,F1 wherein R1 , R2 and R3 are aryl or di-(lower-alkyl)-amino and X is halogen, in a lower alkanol in the presence of an alkali metal hydroxide at a temperature of -10 to -50 degrees C, and b) treating the reaction product obtained in step a) in an organic solvent with a compound or a complex of rhodium or palladium other than palladium or rhodium phthalocyanine or a palladium or rhodium compound containing a cyanide ion.
