LYCOPODIUM ALKALOIDS: XIV. FLABELLINE
Canadian Journal of Chemistry, 1963A new alkaloid, C18H28ON2, designated flabelline, has been isolated by countercurrent distribution from the extract of Lycopodium flabelliforme. The structure and stereochemistry of flabelline have been established by its conversion to and preparation from lycopodine.

Biosynthesis of Lycopodium Alkaloids
1973An investigation of the biosynthesis of lycopodine, the major alkaloid of Lycopodium tristachyum, has revealed that L-lysine, but not D-lysine is incorporated into this alkaloid. D-lysine serves as a precursor to pipecolic acid in this species. Sodium malonate has been demonstrated to be a specific precursor to lycopodine, but attempts to verify the ...

Structure of oxolucidine A, a lycopodium alkaloid
Tetrahedron Letters, 1999Abstract A Lycopodium alkaloid, oxolucidine A, was treated with NaBH 4 followed by p -bromobenzoyl chloride to afford a tribenzoate derivative, which was analyzed by X-ray crystallography to establish the stereostructure. The structure of lucidine A was also determined from these results except for the configuration at C-14.

Canadian Journal of Chemistry, 1989
The alkaloids of the club moss Lycopodiumobscurum L., collected in Northern Alberta, have been investigated. The known alkaloids lycopodine, lycodine, clavolonine, dihydrolycopodine, O-acetyldehydrolycopodine, flabelliformine, β-lofoline, lycofoline, and des-N-methyl-α-obscurine were isolated and identified, as were the known compounds des-N-methyl-β ...

LYCOPODIUM ALKALOIDS: XVI. ANNOTINE
Canadian Journal of Chemistry, 1964Annotine, C16H21O3N, is shown to be pentacyclic and to contain a tertiary hydroxyl group, a lactone function, a tertiary nitrogen atom, and a dialkylated double bond. The position of the double bond and the tertiary hydroxyl group relative to the nitrogen atom has been established by Emde degradation of annotine methiodide.

An approach to the synthesis of Lycopodium alkaloids.
2009The syntheses of a number of new [3.3.1]bicyclononane derivatives are described. Representative compounds include 1-cyano-3-methyl-4-hydroxybicyclo[3.3.1]nonan-9-one, 1-amino-3-methyl-4,9-dihydroxybicyclo[3.3.1]nonane, ethyl-7-methylbicyclo[3.3.1]non-3-en-9-one-1-carboxylate, as well as the following derivatives of ethyl-bicyclo[3.3.1]non-3-en-9-one-1 ...
