A method for preparing chiral γ-secondary amino alcohol includes: adding into a solvent an acid addition salt of β-secondary amino ketone represented by general formula (1), an alkali, a metal salt additive and a diphosphine-rhodium complex, so as to carry out a reaction in a hydrogen atmosphere and obtain a chiral γ-secondary amino alcohol compound represented by general formula (2). In general formula (2), Ar represents an aryl group with or without substituent group(s), R represents an alkyl group or an aralkyl group, and HY represents an acid. The synthesis scheme has a simple process, the metal salt additive remarkably improves the effect of a rhodium-catalyzed asymmetric hydrogenation technology, and accordingly, the reaction yield and the optical purity of a product are improved, the production process is simplified, production costs are reduced, and the synthesis scheme is highly suitable for mass industrial production.

IntramolecularDiels–Alderreaction of trienes (8) gives the octahydroisoquinolones (10) which are readily converted into the biologically-active (12), a substructure of morphine.
