Enantioselective synthesis of (+)-anatoxin-a via enyne metathesis

A concise synthesis of the potent nAChR agonist (+)-anatoxin-a (1) has been completed by a series of nine chemical operations and in 27% overall yield from commercially available D-methyl pyroglutamate (12). The strategy featured the application of a new protocol for the diastereoselective synthesis of cis-2,5-disubstituted pyrrolidines bearing unsaturated side chains and an intramolecular enyne metathesis to provide the bridged bicyclic framework of 1. Thus, D-methyl pyroglutamate (12) was converted in five steps to 32, which underwent facile enyne metathesis to deliver the bicyclic diene 33. Selective oxidative cleavage of the less substituted carbon-carbon double bond in 33 followed by deprotection furnished (+)-anatoxin-a (1).
