Abstract
An x-ray crystal structure determination of veatchine, a C20-diterpenoid alkaloid, reveals the coexistence of molecules which differ in configuration at one of seven asymmetric carbon atoms. This disorder between epimers demonstrates the stability of both forms, and accounts for the doubling of certain peaks in the magnetic resonance spectra of this and related alkaloids.Keywords
