Efficient asymmetricSuzuki-Miyaura coupling of ortho-bromo aryl triflates with various arylboronic acids were described, providing a series of chiralbiaryl triflates in high yields and up to 91% ee under mild conditions. The aryl triflates could be easily transformed to various chiralbiaryl products by further derivatization. A one-pot tandem asymmetriccross-coupling/cross-coupling sequence was
