Constitution of Conessine

Article metrics

Abstract

PREVIOUS work has shown that the alkaloid, conessine, is a ditertiary base, C24H40N2, containing three N-methyl groups and one ethylenic linkage, and our work now establishes a relationship with the growing class of steroid bases. The absence of oxygen is noteworthy ; this is uncommon in the alkaloids, and the natural occurrence of an oxygen-free steroid derivative has not been reported previously.
