Preparation of chiral primary amine from asymmetric reductive amination of simple ketone catalyzed by ruthenium-diphosphine catalyst

The present invention relates to a preparation method of chiral primary amine. The chiral primary amine is prepared through a one-pot method that under the action of a ruthenium-chiral diphosphine catalyst, a simple ketone and an ammonium salt RCOONH.sub.4 have reductive amination by adding hydrogen and then are heated and hydrolyzed by adding acid. The present invention has the advantages of good substrate universality, high reaction efficiency and the like ##STR00001##
