Palladium-catalyzed cross-coupling reactions of neopentyloxysulfonylphenyl bromides with arylboronic acids provided a variety of neopentyl biphenylsulfonates in good yields. 2-Bromo- and 4-bromobenzenesulfonates underwent the coupling reaction more rapidly than 3-bromobenzenesulfonate, while chlorobenzenesulfonate did not produce the coupling product under the standard reaction conditions.

A formal synthesis of Lespedezol $A_1$ has been accomplished. The key feature of this synthesis involves an efficient and powerful palladium-catalyzed cross coupling reaction of diazocarbonyl compound with bis(benzyloxy)phenylboronic acid for the key 3-aryl-chromen-4-one intermediate, which was difficult to be prepared by Suzuki coupling reaction in the previous study. The versatile and efficient synthetic procedure would facilitate synthesis of pterocarpenes and their derivatives.
