Boron–Heck Reaction of Cyclic Enaminones: Regioselective Direct Arylation via Oxidative Palladium(II) Catalysis
摘要:
An oxidative boron Heck reaction of cyclic enaminones with arylboronic acids is reported. This protocol provides a regioselective arylation it the C6 position of cyclic enaminones. When an N-carbamylated cyclic enaminone was employed, a switch to a conjugate addition reaction occurred in the presence of acid.
