Dibenzofuran-4-boronic acid Chemical Properties,Uses,Production
Description
Dibenzofuran-4-boronic acid (DBFBA) is a boronic acid that has been used as a cross-coupling agent in the Suzuki coupling reaction. It has been shown to have low efficiency, but advances in this area have been made through the use of methanol extraction and photophysical properties. DBFBA is often coupled with imidazole derivatives to form anti-inflammatory compounds. The bond cleavage and hydrogen bonding properties of DBFBA make it a good target for drug synthesis.
Chemical Properties
off-white to beige powder
Uses
Dibenzofuran-4-boronic acid is a water-soluble boronic acid, and the boronic acid molecule is a very useful functional group for the preparation of glycosensors. Water-soluble boronic acids that change their fluorescence properties upon binding to sugars are particularly useful as reporter units for carbohydrate fluorescence sensors. Dibenzofuran-4-boronic acid displays distinctive fluorescence changes at three wavelengths when bound to sugars under near-physiological conditions[1].
Synthesis
In a 300 ml three-necked flask, 7.2 g of 4-bromodibenzofuran was dissolved in -78° C. anhydrous tetrahydrofuran (THF) under an argon atmosphere. Then, 20 ml of an n-butyl lithium-n-hexane solution (1.6 M, 1.1 eq) was added and stirred for 1 hour. 4.23 ml (1.3 eq) of trimethoxyborane (B(OMe)3) was added and stirred for 2 hours, and the temperature of the reaction system was increased to room temperature. 200 ml of 1 N hydrochloric acid was added into the reactant and stirred for 3 hours. An organic layer was separated, and solvents were distilled off. In the crude product thus obtained, hexane was added. Precipitated product was filtered to obtain 4.94 g of dibenzofuran-4-boronic acid as a white solid (yield 80%).
