Boronic acids often function as inhibitors for various enzymes due to their unique electronic and physicochemical properties. B-hydroxy-1,2-oxaborolanes (benzoboroxoles) are a class of cyclic boronic acid derivatives and are highly important organic synthons because of their structural stability and their ability to undergo important C-C bond forming reactions such as Suzuki cross coupling. Several of these cyclic boronic acids are found to possess excellent pharmacological properties as antifungal, antimalarial and anti-inflammatory agents. However, the existing literature methodologies for the synthesis of highly functionalized benzoboroxoles are difficult and often are not suitable for large scale synthesis. We have been working on the development of novel synthetic methodologies for the synthesis of functionalized benzoxaboroles as potential therapeutic agents. Previously, we have synthesized several benzoxaboroles employing Baylis-Hillman, Barbier allylation, and Passerini reaction protocols. In continuation of our interest on the development of structurally diverse benzoboroxoles, we synthesized several novel derivatives starting from 2-formylphenylboronic acid utilizing aldol reaction as the key step. Our studies in this area including the synthesis and structural characterization data will be presented.","abstract_html":"Boronic acids are extremely valuable compounds that have applications in medicinal, and materials chemistry, and also as cross-coupling agents in synthetic chemistry.
