Rh(III)-catalyzed umpolung amidation of alkenylboronic acids for the synthesis of enamides is reported. This reaction proceeds readily at room temperature and displays an extremely wide spectrum of functional group tolerance. With cooperation of hydroboration, it enables the formal anti-Markovnikov hydroamidation of terminal alkynes, stereospecifically affording the trans-enamides in excellent yields.
