Dutch Resolution is the term given to the use of mixtures (families) of resolving agents in classical resolutions. In this status report an overview is given of the latest results and new (possible) families of resolving agents are introduced. The concept of families is discussed as well as the factors that come into play on use of families. Practical aspects of Dutch Resolution in particular and resolutions in general are discussed.

The present invention relates to an improved process for preparing enantiomerically pure 3-hydroxy-3-phenyl-propylamines on an industrial scale using asymmetrical hydrogenation as a key step and optionally a special sequence of subsequent steps, using a catalyst system consisting of rhodium and chiral 4-(dicyclohexylphosphino)-2-(diphenyl-phosphino-methyl)-N-methyl-aminocarbonyl-pyrrolidine.

N-(Methylcarbamoyl)-4-(dicyclohexylphosphino)-2-[(diphenylphosphino)methyl]pyrrolidine (MCCPM)- and N-(tert-butoxycarbonyl)-4-(dicyclohexylphosphino)-2-[(diphenylphosphino)methyl]pyrrolidine (BCPM)-rhodium(I) complexes werer efficient catalysts for asymmetric hydrogenations of β- and γ-amino ketone hydrochloride derivatives. Utilizing this methodology, we have developed efficient syntheses of fluoxetine and eprozinol from intermediate optically active amino alcohols.
