摘要: A novel process for preparing an optically active amine by asymmetric hydrogenation of an imine compound, such as an imine compound prepared by condensing benzylamine and acetophenone, in the presence of a catalytic amount of an iridium-optically active phosphine complex and benzylamine or a benzylamine derivative. The present invention provides an optically active amine of high optical purity.

摘要: A process for the preparation of enamines or imines by isomerization of allylamine derivatives is described. Allylamine derivatives represented by formula (I): ##STR1## are isomerized using as a catalyst a rhodium complex represented by formula (IV):[Rh(olefin)L].sup.+ X.sup.- (IV)to form enamines or imines represented by, respectively, formula (II) or formula (III): ##STR2## All of the symbols in the above formulae are as described. These enamines or imines are useful intermediates for the preparation of a number of organic compounds.
