Early warning systems for monitoring toxic events may benefit from the availability of monoclonal antibodies enabling the sensitive and specific detection of anatoxin-a, a cyanotoxin involved in numerous cases of animal poisoning resulting from toxic alga
Synthesis of (±)-anatoxin-α and analogues

A new and highly efficient synthesis of the potent nicotinic acetylcholine receptor agonist, anatoxin-α and its analogues is described, which uses a β-lactam ring opening-transannular cyclisation sequence to set up the bridged bicyclic framework of the natural product. The synthesis involves a cycloaddition of chlorosulfonyl isocyanate with cyclooctadiene followed by Boc protection of the resulting β-lactam. Reaction of the β- lactam with a variety of nucleophiles, followed by selenium-mediated cyclisation and oxidation gave the skeleton of anatoxin-α bearing various sidechains. The approach offers a flexible entry to useful quantities of anatoxin-α and its analogues.
