• The naturtal l-β-hydrastine (Iβ) was epimerized to l-α-hydrastine (Iα). Iα was converted to(--)-canadine (VIII), througth ophiocarpine (VIα), whereas Iβ transformed into VIII through 13-epiophiocarpine (VIβ). The absolute configration of ophiocarpine and 13-epiophiocarpine are represented by VIα(13R : 13aR) and VIβ(13S : 13aR), respectively. Accordingly, the absolute configuration of l-α-hydrastine and l-β-hydrastine are also designated as Iα (αR : 1R)and Iβ(αS : 1R). respectively.
