通过一系列铁催化光氧化还原从草酰胺酸生成氨基甲酰自由基、将氨基甲酰自由基添加到缺电子烯烃、分子内环化、和芳构化。该工艺与多种N-苯基肟酸和单取代、1,1-二取代和三取代的缺电子烯烃相容。该方案采用廉价、易得且环境友好的铁作为催化剂,为 3,4-二氢喹啉-2(1 H )-酮的合成提供了一种极好的替代方案。
Since the advent of antibody checkpoint inhibitors as highly efficient drugs for cancer treatment, the development of immunomodulating small molecules in oncology has gained great attention. Drug candidates targeting IDO1, a key enzyme in tryptophan metabolism, are currently under clinical investigation in combination with PD-1/PD-L1 agents as well as with other established anti-tumor therapeutics
