Abstract
Microwave-assisted divergent domino reactions between cyclic 2-diazo-1,3-diketones and aniline derivatives selectively leading to either glutaramides, piperidino[1,2-a]benzimidazol-1-ones or N-cyclopentenyl benzimidazolones are described. This synthetic protocol features easy operation, a short reaction time, and environmental friendliness.
