Synthesis of 2‐(2‐Hydroxyaryl)‐4H‐benzo[e][1,3]oxazin‐4‐ones by Palladium‐Catalyzed C(sp2)−H Hydroxylation via Electro‐chemical Oxidation

An electrochemical direct ortho‐hydroxylation of 2‐aryl‐4H‐benzo[e][1,3]oxazin‐4‐ones was developed with Pd(OAc)2 as catalyst, oxazine ring as a directing group and Oxone as the hydroxylation reagent. A series of hydroxylation products were obtained under mild conditions, and the yields were from me...
