Two-directional synthesis and biological evaluation of alkaloid 5-epi-cis-275B′Tools Procopiou, George, Aggarwal, Pooja, Newton, Annabella F., Richards, David, Mellor, Ian R., Harbottle, Gareth and Stockman, Robert A.

ISSN 1364-548X Full text not available from this repository.AbstractThe first total synthesis of myrmicine ant alkaloid 5-epi-cis-275B0 (4) is presented. A tandem cyclisation stablished the entire core of the structure in a single transformation as well as the required 2,5-anti stereochemistry. Two-directional synthesis was used to furnish the cyclisation precursor 2, as in each of the subsequent steps towards the natural product. The first electrophysiology studies for 4 (against nicotinic acetylcholine receptors) were also conducted, finding modest inhibition of current.
