Two Daphniphyllum alkaloids with unprecedented polycyclic skeletons, daphnicyclidins J (1) and K (2), have been isolated from the stems of Daphniphyllum humile, and the structures and relative stereochemistry were elucidated on the basis of spectroscopic data. The absolute stereochemistry of 1 was established by chemical correlation with a known-related alkaloid, daphnicyclidin D (3), through a modified Polonovski reaction.

Two cytotoxic quaternary Daphniphyllum alkaloids with an unprecedented fused-polycyclic skeleton containing a 1-azoniatetracyclo ring system, daphniglaucins A (1) and B (2), have been isolated from the leaves of Daphneglaucins glaucescens and their structures were elucidated on the basis of spectroscopic data.

Secophnane‐Type Alkaloids from Daphniphyllum oldhami

Four new alkaloids, daphnioldhanins D–G (1–4, resp.), together with five known alkaloidal substances, were isolated from the roots of Daphniphyllum oldhami and showed potent antioxidant activity against H2O2‐induced impairment in PC12 cells.
