The Suzuki-Miyaura reaction has become one of the more useful tools for synthetic organic chemists. Until recently, there did not exist a direct way to make the most important component in the coupling reaction, namely the boronic acid. Current methods to make boronic acids often employ harsh or wasteful reagents to prepare boronic acid derivatives and require additional steps to afford the desired boronic acid. The scope of the previously reported palladium-catalyzed, direct boronic acid synthesis is unveiled, which includes a wide array of synthetically useful aryl electrophiles. It makes use of the newly available second generation Buchwald XPhos preformed palladium catalyst and bis-boronic acid. For ease of isolation and to preserve the often sensitive C-B bond, all boronic acids were readily converted to their more stable trifluoroborate counterparts.

A compound represented by the formula (I) or a salt thereof: wherein n represents an integer of 1 to 3, R represents an alkyl group having 3 to 8 carbon atoms, a group represented by the following formula: R1(CH2)k— (wherein k represents 0 or an integer of 1 to 3; R1 represents a saturated cyclic alkyl group having 3 to 7 carbon atoms or a saturated condensed cyclic alkyl group having 6 to 8 carbon atoms, and the group R1 may be substituted with a lower alkyl group having 1 to 4 carbon atoms) and the like, and Ar represents a condensed bicyclic group such as naphthalen-1-yl group, which has suppressing action on prostaglandin and leukotriene production and is useful for prophylactic and/or therapeutic treatment of various inflammatory diseases and the like caused by these lipid mediators.
