• Dihydroimidazole
• Carbenoid
• Dihydroimidazolium ylide
• Dipolar cycloaddition
• Pyrrroloimidazole

A catalytic method involving carbenoid insertion onto dihydroimidazoles is reported for the generation of dihydroimidazolium ylides, and their subsequent diastereoselective cycloaddition to form pyrrolo[1,2-a]imidazoles.
