Abstract

Abstract: The palladium-catalyzed coupling reaction of aryl triflates with alkyl, vinyl, acetylenic, and aryl tin reagents in the presence of lithium chloride takes place in high yields under mild conditions. However, allyltrialkyltin reagents coupled in lower yields, and unselective transfer of the allyl group was observed. The aryl coupling reaction was applied to a synthesis of the quinoline alkaloid dubamine. The palladium-catalyzed coupling of ...
