Boronic acids are an increasingly important compound class for many applications, including C–C bond formation reactions, medicinal chemistry, and diagnostics. The deprotection of boronic ester intermediates is frequently a problematic and inefficient step in boronic acid syntheses. We describe an approach that highly facilitates this transformation by leveraging the volatility of methylboronic acid and

Peptides and peptidomimetics with a C-terminal boronic acid group have prolific applications in numerous fields of research, but their synthetic accessibility remains problematic. A convenient, high yield synthesis of peptide-boronic acids on a solid support is described here, using commercially available 1-glycerol polystyrene resin. The method is compatible with Fmoc chemistry and offers a versatile
