The present invention provides compositions of 6-amino morphinan compounds and process for their synthesis. In particular, the processes provide for the reductive amination of 6-keto morphinans by catalytic transfer hydrogenation, to produce 6-amino morphinan compounds, which are epimerically and/or diastereomerically enriched.

A phytochemical investigation for the rhizome extract from Sinomenium acutum (Menispermaceae) resulted in the isolation of several active principles responsible for the anti-osteoclastogenic property of the extract, together with related isoquinoline alkaloids (1–13) including two new compounds, 1 and 2. Among isolated compounds, salutaridine (7), dauricumine (10), cheilanthifoline (12), and dauriporphine
