Palladium-Catalyzed β-Acyloxylation of Simple Amide via sp3 C–H Activation
摘要:
beta-Acylcoxy amides are prepared in moderate to high yields by palladium-catalyzed acyloxylation of primary sp(3) C-H bonds from simple amides without any special directing group. A catalytic system of Pd(OAc)(2)/CF3CO2H/K2S2O8 is available to various amides with N-substituted by linear alkanes, cyclic alkanes, and electron-deficient benzyl compounds in this reaction. Acyloxylated products could be transformed easily to the corresponding beta-hydroxy amides.
