Lycoplanines B-D, Three Lycopodium Alkaloids from Lycopodium complanatum

A novel C17N Lycopodium alkaloid (LA), lycoplanine B (1), containing an unusual formyl group, along with two new LAs, lycoplanines C (2) and D (3), were isolated from the whole plant of Lycopodium

Lyconadins G and H, Two Rare Lyconadin-Type Lycopodium Alkaloids from Lycopodium complanatum

It is the first time to establish the absolute configuration of lyconadin-type Lycopodium alkaloid by an X-ray diffraction experiment and may provide more information for the biosynthesis of Lyconadins.

Lycopodium Alkaloids from Diphasiastrum complanatum

One new lycopodine-type Lycopodium alkaloid, dehydroisofawcettiine N-oxide (1) and eleven known analogues (2–12) were isolated from the whole plant of Diphasiastrum complanatum. The new structure was

Lycojaponicumins A-C, three alkaloids with an unprecedented skeleton from Lycopodium japonicum.

Lycojaponicumins A-C (1-3), three trace alkaloids isolated from Lycopodium japonicum, represent a unique heterocyclic skeleton formed by the new linkage C4-C9, and are the first examples of natural products possessing a 5/5/5 /5/6 pentacyclic ring system with a 1-aza-7-oxabicyclo[2.2.1]heptane moiety.

Synthetic studies on pseudo-dimeric Lycopodium alkaloids: total synthesis of complanadine B.

Complanadines A and B (1 and 2, Figure 1) are dimeric Lycopodium alkaloids in the lycodine family that possess significant activity for nerve growth factor (NGF) production from human glial cells.i,
