Adducts of peptides and arylboronic acids are attractive tools
for the selective recognition of carbohydrates. These structures
resemble at least some of the properties of natural carbohydrate
binders and have therefore been termed lectin mimetics or boronolectins.
In this report, we describe the synthesis of appropriately functionalized
benzoboroxoles as modular components for the assembly of boronolectins.
These benzoboroxoles have been prepared in a few steps from readily
available starting materials. In conclusion, versatile functionalized
benzoboroxoles are reported that can be used for the construction
of larger conjugates by peptide coupling or copper-mediated cycloadditions
(click reactions) with azides.
