Intramolecular substitution by oxygen nucleophiles at N-benzenesulphonylindole β-positions, with loss of benzene sulphinate, and the use of this novel process for the synthesis of oxepino[2,3:b]indoles are described.

sequences involving the first examples of intramolecular nucleophilicsubstitution at an indoleβ-position, with departure of phenylsulphinate as leaving group from nitrogen. The spectroscopic and chemical evidence supporting the structures for these new heterocyclic systems, and thus by implication the operation of indole β-nucleophilic substitution, are detailed.
描述了[2]苯并xepino [4,3 - b ]吲哚-11(6 H,12 H)-one,(12a)和12-甲基吡啶并[4',3':3,4] oxepino [3 ,2 - b ]吲哚-5(6 H,12 H)-one,(5),通过涉及吲哚β-位的分子内亲核取代的第一个例子的序列,苯磺酸盐作为离去基团离开氮。光谱和化学证据支持了这些新杂环系统的结构,并因此暗示了吲哚β-亲核取代的操作。
