Abstract
A hydroxy group directed keto α-Csp3–H benzoxylation of amides, including N,N-dialkylamides and cyclic amides, has been accomplished involving ortho-hydroxy substrates possessing either an aldehydic or a keto methyl (–COCH3) group with a Pd(II)/CuBr2 catalytic combination. The carboxy group obtained via the in situ oxidation of –CHO or –COCH3 groups of ortho-hydroxy substrates then undergoes a Cross-dehydrogenative Coupling (CDC) with amides to furnish an α-benzoxylation product with concurrent aromatic ring bromination.
