Regioselective 7- and 8-endo cyclizations of selenoester derived 2-indolylacyl radicals upon amino tethered alkenes have been used to synthesize azepino[3,2-b]- and azocino[4,3-b]indoles, which are tricyclic subunits present in the indole alkaloids mersicarpine and apparicine, respectively.
硒酯衍生的2-吲哚基基团在氨基系链烯烃上的区域选择性7和8内环化反应已用于合成氮杂环庚烷[3,2- b ]-和偶氮基[4,3- b ]吲哚,它们是存在于三环亚基中的三环亚基吲哚类生物碱美卡西平和Apparicine。
