Radical-mediated acyl thiol-ene reactions between biologically relevant alkene and thioacid components enables rapid, chemoselective and high yielding thioester formation. This reaction in combination with substrates that enable intramolecular acyl transfer permits access to native and modified products beyond the thioether linkage.

A structurally distinct and potent series of synthetic small molecule activators of Vibrio cholerae quorum sensing have been chemically synthesized. The small molecule activators reduce virulence in V. cholerae. Acyl pyrrole molecules displayed strong potency and stability, particularly l-(1H-pyrrol-3-yl)decan-l-one.
