protocol for the preparation of cycloalkano[1,2-a]indoles by way of an intramolecular alkylmigration reaction in cyclic indolylborates is described. NaOMe was found to act as a successful trialkylboryl-protecting group against to the lithiation at the C2 of the indole ring. Treatment of cyclic indolylborates with electrophiles produced cycloalkano-[1,2-a]indoles.
描述了一种新颖的一锅法,用于通过环状吲哚硼酸酯中的分子内烷基迁移反应制备环烷[1,2- a ]吲哚。发现NaOMe可作为成功的三烷基硼基保护基团来抵抗吲哚环C2上的锂化。用亲电试剂处理环状吲哚硼酸酯产生环烷-[1,2- a ]吲哚。
