The X-ray diffraction analysis of 30 C19-diterpenoid alkaloids is reviewed. During the course of structure determination, many naturally-occurring alkaloids have been correlated with alkaloids whose structures were established by X-ray crystal studies. The relative stereochemistry of these alkaloids at all the centres can be assumed to be correct. The absolute stereochemistry has been established for some of the alkaloids.
