Epoxy-sulfonamides react with heterocumulenes (carbon disulfide/isothiocyanates/isocyanates) in the presence of a base to afford ring expansion products in good to high yields with excellent regioselectivity. N-(2-Bromoethyl)-sulfonamides can also be employed as substrates. This reaction proceeds through a 5-exo-tet pathway without forming aziridine intermediates.

This imaging method of AMPA receptors in the brain of primate organisms involves a step in which a substance which is administered to the primate organism and which selectively bonds to AMPA receptors in the brain of the primate organism and has a radiolabel is transported into the brain and made to bond with AMPA receptors in the brain, and, by detecting radiation emitted from the substance bonded to the AMPA receptors in the brain, data is obtained relating to the distribution and/or expression level of the AMPA receptors in the brain.
