Oxone promoted intramolecular dehydrogenative imino Diels–Alder reaction (Povarov cyclization) of alkyne tethered N-aryl glycine esters and amides has been explored, thus affording biologically significant quinoline fused lactones and lactams. The reaction is simple, scalable, and high yielding (up to 88%). The method was further extended to prepare biologically important luotonin-A analogues and the
已经探索了Oxone 促进了炔烃连接的N-芳基甘氨酸酯和酰胺的分子内脱氢亚氨基 Diels-Alder 反应(Povarov 环化),从而提供了具有生物学意义的喹啉稠合内酯和内酰胺。该反应简单、可扩展且产率高(高达 88%)。该方法进一步扩展到制备具有生物学重要意义的luotonin-A类似物和环沙霉素的喹啉核心。
