  • Title: Reversible click reactions with boronic acids to build supramolecular architectures in water.
    Author: Arzt M, Seidler C, Ng DY, Weil T.
    Journal: Chem Asian J; 2014 Aug; 9(8):1994-2003. PubMed ID: 24764166.
    Abstract:
    The interaction of boronic acids with various bifunctional reagents offers great potential for the preparation of responsive supramolecular architectures. Boronic acids react with 1,2-diols yielding cyclic boronate esters that are stable at pH>7.4 but can be hydrolyzed at pH<5.0. The phenylboronic acid (PBA)-salicylhydroxamic acid (SHA) system offers ultra-fast reaction kinetics and high binding affinities. This Focus Review summarizes the current advances in exploiting the bioorthogonal interaction of boronic acids to build pH-responsive supramolecular architectures in water.
