Pd(II)-catalyzed intermolecular 1,2-aminooxygenation and 1,2-oxyamination of conjugated dienes 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
已经开发了Pd(II)催化的共轭二烯的分子间1,2-氨基加氧和1,2-氧胺化。通过调节配位溶剂可以完成多种2官能化和3官能化的1,4-苯并恶嗪衍生物的化学选择性制备。氧气已成功用于烯烃的氧化双官能化。大多数产品都具有良好的收率和选择性。还从2,3-二取代的1,3-二烯获得带有螺线结构的产物。
