Concerning the preparation of 6-bromotryptamine

Most of the previous syntheses of the marine natural product 6-bromotryptamine have almost certainly led to partial debromination resulting in an impure product containing tryptamine. We show that loss of bromine occurs when lithium aluminum hydride is employed as a reducing agent in the final reaction step leading to 6-bromotryptamine. Reductive-debromination is also likely to intrude during some of the syntheses of 6-bromoindole, the typical precursor to 6-bromotryptamine. None of the seven described syntheses of 6-bromotryptamine that involve a reduction sequence from 6-bromoindole have reported elemental analyses as a measure of purity.

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 between 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.
