A metal- and additive-free, highly efficient, step-economical deoxygenative C2-heteroarylation of quinolines and isoquinolines was achieved from readily available N-oxides and N-sulfonyl-1,2,3-triazoles. A variety of α-triazolylquinoline derivatives were synthesized with good regioselectivity and in excellent yields under mild reaction conditions. Further, a gram-scale and one-pot synthesis illustrated
通过容易获得的N-氧化物和N-磺酰基-1,2,3-三唑可实现喹啉和异喹啉的无金属和无添加剂,高效,经济的步骤脱氧C2-杂芳基化。在温和的反应条件下,以良好的区域选择性和优异的产率合成了多种α-三唑基喹啉衍生物。进一步,克级和一锅法合成说明了所开发协议的有效性和简单性。还发现当前的转化与天然产物的后期改性相容。
