Abstract

A new isoquinoline alkaloid, jamtine-N-oxide has been isolated from Cocculus hirsutus. Its structure has been assigned as C20H25NO5 (1) on the basis of spectral studies. Its stereochemistry has been determined by homonuclear 2D 1H-NMR (COSY-45, J-resolved, NOESY) and 13C-NMR assignments made by GASPE experiments. © 1987.
