3-b]furan-4,9-diones has been developed by N-iodosuccinimide (NIS)-induced enone difunctionalization with 2-hydroxy-1,4-naphthoquinones. This reaction involved sequential Michael addition, intramolecular oxidative cyclization and dehydrogenative aromatization to form new C–C and C–O bonds at the α and β positions of the enones. Various enones survived under the reaction conditions and the corresponding products
萘并[2,3-b]呋喃-4,9-二酮的有效合成已通过N-碘代琥珀酰亚胺(NIS)诱导的烯酮双官能化与2-羟基-1,4-萘醌进行合成。该反应涉及连续的迈克尔加成、分子内氧化环化和脱氢芳构化,以在烯酮的 α 和 β 位置形成新的 C-C 和 C-O 键。各种烯酮在反应条件下幸存下来,并以中等至优异的收率获得相应的产物。
