The alkaloids of <i>L. magellanicum</i> and the structure of magellanine

Abstract

Examination of the alkaloids of Lycopodium magellanicum (Palisot de Beauvois) has revealed the presence of five alkaloids of established structure and a previously unreported alkaloid, magellanine (C 17 H 25 NO 2 ). The ring System of magellanine, deduced from an examination of its spectroscopic properties, is identical with that of paniculatine. The structure of magellanine has been confirmed, and its relative stereochemistry established, in an X-ray crystallographic study.
