Pd(II)-catalyzed intermolecular 1,2-aminooxygenation and 1,2-oxyamination of conjugateddienes have been developed. The chemoselective preparation of a variety of 2-functionalized and 3-functionalized 1,4-benzoxazine derivatives was accomplished via the adjustment of a coordinating solvent. Oxygen was successfully used in this oxidative difunctionalization of alkenes. Good yields and selectivities
