have a great influence upon the reaction. By using C2-methyl- and C2-phenyl-3-(1H-indol-3-yl)-N-alkoxypropanamide as templates, practical protocols for the divergent synthesis of fused- and spirocyclicindoline compounds were studied and established.
描述了NBS 诱导的 3-(1 H -indol-3-yl) -N -alkoxypropanamide 的分子内环化。在碱的帮助下,反应在温和的条件下进行得很好而且很快。发现3-(1H - indol-3-yl)-N - alkoxypropanamide中吲哚环上的C2-取代基对反应有很大的影响。以 C2-methyl- 和 C2-phenyl-3-(1 H -indol-3-yl) -N -alkoxypropanamide 为模板,研究并建立了稠环和螺环二氢吲哚化合物的发散合成实用方案。

Iodine(III)-Mediated C–C Bond Coupling to Construct Spirocyclic Indolenines of Various Ring Sizes
iodine(III)-mediated intramolecular dearomative spirocyclization of indole derivatives to generate highly strained spirocyclobutyl, spirocyclopentyl, and spirocyclohexyl indolenines in moderate to good yields. A set of structurally novel, densely functionalized spiroindolenines with broad functional group compatibility was efficiently constructed in this way under mild reaction conditions. Moreover
