Five new trace alkaloids with fawcettimine-related structures (1–5), i.e., 6-hydroxyl-6,7-dehydrolycoflexine (1), 6-hydroxyl-6,7-dehydro-8-deoxy-13-dehydroserratinine (2), together with three known ones (6–8), were isolated from the club moss Lycopodium japonicum Thunb. Their structures were elucidated by extensive NMR spectroscopic analysis, HRESIMS, CD and comparison with known ones. Compounds 1 and 2 are characterized by the enol moiety that is rarely reported in Lycopodium alkaloids, and Compound 5 is the second example of Lycopodium alkaloids with a C-16–C-4 linkage. A plausible biogenetic pathway for the isolates was proposed.
