an important heterocyclic scaffold in natural product, bioorganic, and medicinal chemistry as well as in materials science. The system S8/DABCO/DMSO was found to efficiently mediate the oxidative cyclization of 1,2,3,5-tetraarylpentan-1-ones A, which were obtained in situ as the Michael adducts of chalcones 1 and deoxybenzoins 2, to furan 3. The strategy provided convenient and direct access to tetrasubstituted
呋喃是天然产物、生物有机、药物化学以及材料科学中重要的杂环支架。发现系统 S 8 /DABCO/DMSO 可以有效介导 1,2,3,5-四芳基戊烷-1-酮A的氧化环化,该化合物是作为查尔酮1和脱氧苯偶姻2的迈克尔加合物原位获得的,生成呋喃3 . 该策略提供了从易于获得的具有高官能团耐受性的起始材料中方便、直接地获得四取代呋喃3 的方法。
