Magellanine

(−)-Magellanine is a member of the Lycopodium alkaloid class of natural products. It was isolated from the club moss Lycopodium magellanicum in 1976.^[1] It has been synthesized five times, with the first synthesis having been completed by the Larry E. Overman group at the University of California, Irvine in 1993.^[2] It has also been synthesized by the Leo Paquette group in 1993 at Ohio State University,^[3] the Chun-Chen Liao group in 2002 at National Tsing Hua University,^[4] the Miyuki Ishikazi and Tamiko Takahashi groups in 2005 at the Josai International University and Tokyo University of Science,^[5] and the Chisato Mukai group in 2007 at the Kanazawa University.^[6] One partial synthesis was completed by the A. I. Meyers group in 1995 at Colorado State University.^[7]

Biosynthetically, it is thought to have been derived from lysine. This was determined by conducting feeding studies of radiolabeled precursors.^[8]
