generated at the C-7 position of ethyl indole-2-carboxylates bearing N-allyl and propargylic groups triggered intramolecular cyclizations to furnish a new class of Duocarmycin analogues, formal ethyl pyrrolo[3,2,1-ij]quinoline-2-carboxylate derivatives, through the less favorable 6-endo-trig cyclization mode.
在带有 N-烯丙基和炔丙基的吲哚-2-羧酸乙酯的 C-7 位产生的芳基自由基引发分子内环化,以提供一类新的双癌霉素类似物,正式的乙基吡咯 [3,2,1-ij] 喹啉 - 2-羧酸衍生物,通过不太有利的 6-endo-trig 环化模式。
