    Introduction:

    5-Formaldehyde-furan-2-boronic acid is a beige to brown powdery substance that can be used in pharmaceuticals and dyes. Applications 5-Formaldehyde-furan-2-boronic acid is a boric acid intermediate and is widely used in medicine and other fields. Boric acid compounds can undergo Suzuki reactions with chlorine, bromine or iodinated aromatics and alkenes, thereby connecting a variety of groups, and the downstream products are very rich.

    Preparation of 5-carboxaldehyde-2-boronic acid from 2-furancarbaldehyde-ethylene glycol, triisopropyl borate and sodium powder in THF: Pre-place 1.81g of sodium powder (pellets) in an inertized 250ml Schlenk flask diameter <100 μm), 12 mg biphenyl and 120 g THF. After stirring at room temperature for 15 minutes, the water is cooled to an internal temperature of 5-10°C and a composition consisting of 14.8 g of triisopropyl borate, 5.1 g of isoprene and 10.5 g of 2-furancarboxaldehyde ethylene glycol is added dropwise within 2 hours. mixture. After the metered addition has been completed, the mixture is stirred for another 1 hour at approximately 25° C. and the mixture is poured into approximately 150 g of 15% hydrochloric acid which was stirred and cooled to approximately 0° C. using an ice bath.
