Bioisosteric analogues of pachastrissamine that contain sulfur and selenium atoms replacing the oxygen in the ring system, were efficiently prepared from a cyclic sulfate intermediate by sequential intermolecular and intramolecular SN2 displacement reactions of the dianions. The analogues exhibited cytotoxicities comparable to that of pachastrissamine.
