Optimized conditions for copper-catalyzed N-arylation of methyl pyroglutamate are described. These studies permitted the synthesis of methyl N-naphthylpyroglutamate, which was then cyclized to a ketone. The known dehydration of amidoketones by PPA was extended to this new scaffold to lead to a novel condensed benzo[de]quinoline with potential antioxidative activity.
描述了铜催化焦谷氨酸甲酯N-芳基化的最佳条件。这些研究允许合成N-萘基焦谷氨酸甲酯,然后将其环化成酮。PPA已知的酰胺酮脱水作用已扩展到这种新型支架上,从而产生了一种具有潜在抗氧化活性的新型缩合苯并[ de ]喹啉。
