A new and direct approach to functionalized biaryl α-ketophosphonic acids via aqueous Suzuki coupling on solid support

A new method for the synthesis of functionalized biaryl α-ketophosphonic acids has been developed. The key step involves the use of sodium bromobenzoyl phosphonates to react with polymer-bound boronic acids via microwave-assisted aqueous Suzuki coupling. This approach provides rapid access to a wide range of diverse biaryl analogues containing an α-ketophosphonic acid moiety.
