A convenient method for oxidant-promoted radical cascade acylation or decarbonylative alkylation of 1,7-dienes with aldehydes has been established. This method allows for the rapid construction of N-containing polycyclic skeletons in a highly regio- and stereoselective manner. This transformation provides a simple and efficient method for the preparation of a range of tetrahydro-6H-indeno[2,1-c]quinolinone
已经建立了一种方便的氧化剂促进的自由基级联酰化或 1,7-二烯与醛的脱羰烷基化的方法。该方法允许以高度区域和立体选择性的方式快速构建含氮多环骨架。该转化提供了一种简单有效的方法,通过顺序形成三个新的碳-碳键来制备一系列四氢-6H-茚并[2,1 -c ]喹啉酮衍生物。此外,这种自由基级联环化可以选择性地将醛转化为芳酰基/伯脂肪族酰基和仲或叔烷基。
