Iridium-catalyzed orthogonal and regioselective synthesis of triazole disulfides in aqueous media under mild conditions

An orthogonal and regioselective synthesis of triazole disulfides in aqueous media under mild conditions has been developed. This simple and practical approach is environment-friendly and compatible with oxygen/water and various complex biological media. It features excellent regioselectivities and chemoselectivities, high yields, good biocompatibility and bioorthogonality. Its applications in the synthesis of carbohydrates and trigger-responsive nanoparticles are further highlights of this aqueous transformation.
