A highly diastereoselective one-pot three-component 1,3-dipolar cycloaddition of cyclopropenes with azomethine ylides generated from 11<i>H</i>-indeno[1,2-<i>b</i>]-quinoxalin-11-ones

Abstract

A simple and efficient synthesis of compounds with spiro-fused 11<italic>H</italic>-indeno[1,2-<italic>b</italic>]quinoxaline and azabicyclo[3.1.0]hexane or cyclopropa[<italic>a</italic>]pyrrolizine moieties was developed.
