title: Dirhodium(II)-catalyzed formal [3+2+1]-annulation of azomethine imines with two molecules of a diazo ketone.
abstract: A highly diastereoselective formal [3+2+1]-cycloaddition reaction that produces multi-functionalized bicyclic pyrazolidinone derivatives is achieved in moderate to high yield by Rh2(4S-MPPIM)4-catalyzed reaction of azomethine imines with two molecules of a diazo ketone.
