Abstract

Three new Lycopodium alkaloids, lannotinidines H—J (1—3), were isolated from the club moss Lycopodium annotinum. The structures and relative stereochemistry of 1—3 were elucidated on the basis of spectroscopic data and the absolute stereochemistry of 2 was assigned by chemical correlation. Lannotinidine H (1) is the first Lycopodium alkaloid possessing a lycopodane skeleton with an additional C₃ unit.
