摘要
Two for the price of one: A method has been developed for the regiocontrolled synthesis of multisubstituted biaryl derivatives. This protocol involves the use of the tert-butyldimethylsilyl (TBDMS) group to direct the regioselective Diels-Alder reaction of a 3-TBDMS-benzyne with a furan derivative and a subsequent Hiyama cross-coupling reaction of the TBDMS group with aryl iodides (see scheme). © 2008 Wiley-VCH Verlag GmbH & Co.
