The first example of the reactions of cyclopropenes with N-acyliminium cations is described. 3-(1H-Inden-3-yl)isoindolin-1-ones and cyclopropa[c]isoindolo[2,1-a]quinolones were prepared by BF3·OEt2 mediated reactions of cyclopropenes with the N-acyliminium cations, generated from 2-aryl(benzyl)-3-hydroxyisoindolin-1-ones.
描述了环丙烯与N-酰基亚胺阳离子反应的第一个例子。通过BF 3 ·OEt 2介导的环丙烯与N-酰基亚胺阳离子的反应制备3-(1 H -Inden-3-yl)异吲哚啉-1-酮和环丙烷[ c ]异吲哚并[2,1- a ]喹诺酮,由2-芳基(苄基)-3-羟基异吲哚啉-1-酮生成。
