Crystal structure of two quasi-racemates of (–)-podopetaline and (–)-ormosanine isolated from Podopetalum ormondii; the absolute configuration of (–)-ormosanine
Abstract
A constant m.p. alkaloid fraction obtained from Podopetalum ormondii has been shown by X-ray analysis to contain two polymorphs, one monoclinic, the other triclinic, both being quasi-racemates of (–)-podopetaline and (–)-ormosanine.
