摘要
A straightforward synthesis of the brominated marine alkaloids arborescidine A (1), B (2) and C (3), starting from 6-bromo-(N-methyl) trypatamine is described. An equilibrium, under both basic and acidic conditions was found to exist beta een the trans-and cis-isomers 3 and 4. Spectral data indicated that the structure of isomer 4 does not correspond with the compound identified as arborescidine D recently isolated from the marine tunicate Pseudodistoma arborescens.
