In this paper, a highly efficient copper-catalyzed oxidative dehydrogenative coupling to obtain benzo[c]cinnolines (up to 100% yield) was developed. It was found that DMAP was a highly efficient ligand for copper-catalyzed oxidation, and molecular oxygen was a green oxidizing agent. In this simple process, various functional groups were tolerated under mild reaction conditions, and the practicality
本文开发了一种高效的铜催化氧化脱氢偶联方法来获得苯并[ c ]肉啉(收率高达100%)。研究发现DMAP是铜催化氧化的高效配体,分子氧是绿色氧化剂。在这个简单的过程中,在温和的反应条件下可以耐受各种官能团,并且通过克级苯并[ c ]肉啉的制备和随后的衍生化证明了该过程的实用性。
