LYCOPODIUM ALKALOIDS: PART VIII. NEW ALKALOIDS FROM JAMAICAN LYCOPODIUM SPECIES

Canadian Journal of Chemistry, 1963
Four more alkaloids have been isolated from Lycopodium fawcettii. Lycodine and des-N-methyl-α-obscurine have been found in other Lycopodium species but base L, C18H31NO4, and base R, C16H24N2O2, are new. Some transformations of base L are described including its conversion to the previously described base O. An unstable base from L.

Alkaloids from Lycopodium casuarinoides

Journal of Natural Products, 1994
In addition to huperzinine [1], a new alkaloid, N-demethylhuperzinine [2], was isolated from the aerial parts of Lycopodium casuarinoides by bioassay-directed fractionation. The structure of 2 was established by spectral analysis and extensive nOe difference nmr studies as well as spectral comparison with huperzinine.

The Lycopodium Alkaloids

HETEROCYCLES, 2009
Lycopodium alkaloids are unique heterocyclic alkaloids having C 11 N, C 15 N 2 , C 16 N, C 16 N 2 , C 22 N 2 , and C 27 N 3 types from genus Lycopodium and have attracted great interest from biogenetic and biological points of view as well as providing challenging targets for total synthesis.

Lycopodium alkaloids—II

Tetrahedron, 1962
Abstract Structures VIIa and VIIIa are developed for α- and β-obscurine, respectively. The transformation of α-obscurine (VIIa) into dihydrolycopodine (XII) is described. Since the structure and stereochemistry of the latter is known, the structure and stereochemistry of the obscurines is thereby established and is as shown in XIV.

Lycopodium alkaloids from Huperzia serrata

Fitoterapia, 2019
Five new Lycopodium alkaloids, huperzine Y1 (1), huperzine Y2 (2), huperzine Y3 (3), (+)-huperzine Z (4a) and (-)-huperzine Z (4b) as well as ten known alkaloids (5-14) were isolated from Huperzia serrata. The structures of the new compounds were established using extensive spectroscopic (1D and 2D NMR, IR, and HRESIMS) and calculated electronic ...

Three newLycopodiumalkaloids fromLycopodium obscurum

Journal of Asian Natural Products Research, 2013
Chemical investigation on the crude alkaloid portion of Lycopodium obscurum led to isolation of three new fawcettimine-type Lycopodium alkaloids, lycobscurines A-C (1-3), together with three known compounds. Their structures were determined by spectroscopic methods including HR-ESI-MS and NMR techniques.
