Aryl boronic acids and their esters are amongst the most valuable and widely used intermediates in modern organic synthesis due to their high applicability to formation of C-C, C-N and C-O bonds, etc. These compounds are generally accessed via a functional group interconversion strategy from corresponding aryl halides and triflates. However, the development of alternative synthetic methods has been required for the preparation of a wider range of boronic acid derivatives having various functional groups. In this symposium we are going to present a novel method for the synthesis of multisubstituted aryl boronic acid derivatives based on the unprecedented generation of borylbenzynes and their regioselective Diels-Alder reactions with furans.
