A novel Pd/Cu-catalyzed chemoselective aerobic oxidative N-dealkylation/carbonylation reaction has been developed. Tertiary amines are utilized as a "reservoir" of "active" secondary amines in this transformation, which inhibits the formation of undesired by-products and the deactivation of the catalysts. This protocol allows for an efficient and straightforward construction of synthetically useful
A facile and convenient protocol for the synthesis of cinnamides from cinnamic acids and tetraalkylthiuram disulfides under metal and additive free conditions has been achieved. This method allows the efficient coupling of diverse cinnamic acids with tetraalkylthiuram disulfides through a simply mixing operation.
