The regloselectivity of the Fischer indole synthesis from 2-azabicyclo[3.3.1]nonan-7-ones 4b–d using three different acid catalysts is studied, an ethyl substituent at the 9-position promoting indolization upon the C-8 carbon.
研究了使用三种不同的酸催化剂由2-氮杂双环[3.3.1] nonan-7-ones 4b–d合成Fischer吲哚的区域选择性,其中9位的乙基取代基促进C-8碳上的吲哚化。
