title: Nankakurine A, a novel C16N2-type alkaloid from Lycopodium hamiltonii.
abstract: [sstructure: see text] A novel, fused-tetracyclic Lycopodium alkaloid, nankakurine A (1), consisting of a cyclohexane ring and a 3-aza-bicyclo[3.3.1]nonane ring connected to a piperidine ring through a spiro carbon, was isolated from the club moss Lycopodium hamiltonii. The structure and relative stereochemistry were elucidated on the basis of spectroscopic data.
