Palladium-Catalyzed Cross-Coupling of Acetates of Baylis−Hillman Adducts and Potassium Organotrifluoroborates
摘要:
[GRAPHICS]The cross-coupling of potassium organotrifluoroborates and acetates of Baylis-Hillman adducts proceeds readily in moderate to excellent yield in the presence of Pd(OAc)(2). The reaction tolerates hindered trifluoroborate salts, and the process is stereoselective.
