Palladium-Catalyzed α-Arylation of 2-Chloroacetates and 2-Chloroacetamides
摘要:
A method has been developed for the Pd-catalyzed synthesis of alpha-(hetero)aryl esters and amides through a Suzuki-Miyaura cross-coupling reaction. This method avoids the use of strong base, does not necessitate inert or low temperature formation of reagents, and does not require the use of a large excess of organometallic reagent. Utilization of organotrifluoroborate salts as nucleophilic partners allows a variety of functional groups and heterocyclic compounds to be tolerated.
