Abstract
A simple protocol for the synthesis of Weinreb benzamides and alpha,beta-unsaturated Weinreb amides through a palladium-catalyzed cross-coupling reaction between organoboronic acids and N-methoxy-N-methylcarbamoyl chloride has been developed. The method is also applicable to the use of potassium organotrifluoroborates.
