Diastereomers of Cyclopropa[a]pyrrolizine Spiro-fused with a Benzo[4,5]imidazo[1,2-a]indole Fragment: Structure Determinations Using NMR Methods

NMR spectroscopy methods have been used to prove structures of two diastereomers of cyclopropa[ a ]pyrrolizine spiro-fused with a benzo[4,5]imidazo[1,2- a ]indole fragment which were obtained through a three-component 1,3-dipolar cycloaddition reaction and isolated in a ratio of 6:1. Complete signal...
