Lycochinines A-C, novel C27N3 alkaloids from Lycopodium chinense

Three novel C27N3-type Lycopodium alkaloids, lycochinines A-C (1-3) consisting of an octahydroquinoline or a decahydroquinoline, a quinolizidine, and a piperidine, were isolated from the club moss Lycopodium chinense. The relative stereochemistry of 1-3 was determined by a combination of NOESY correlations and chemical transformations.
