Abstract:
:Fasciospyrinadine (1), a novel sesquiterpene pyridine alkaloid with a previously unreported skeleton featuring a monocyclicfarnesane moiety attached to a 3-methylenepyridine residue, was isolated from the sponge Fasciospongia sp. from Weizhou Island, Guangxi Autonomous Region. The structure and the relative stereochemistry of 1 were elucidated on the basis of extensive analysis of its 1D and 2D NMR spectroscopic techniques.
