Abstract:

Seven new C19-diterpenoid alkaloids, circinasines A-G (1-7), together with six known compounds, talatisamine, yunaconitine, senbusine A, sachaconitine, hemsleyanisine, and isohemsleyanisine, were isolated from the roots of Aconitum hemsleyanum var. circinatum. The structures of 1-7 were determined by the interpretation of spectroscopic data and by the single-crystal X-ray crystallographic analysis of 6 and the acetonide derivative of 1. In addition, the structures of hemsleyanisine and isohemsleyanisine were revised from 8 and 9 to 10 and 11, respectively.

Physical Properties of Amines

Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.
