title: Dirhodium(II) tetrakis[methyl 2-oxaazetidine-4-carboxylate]: a chiral dirhodium(II) carboxamidate of exceptional reactivity and selectivity.
abstract: [formula: see text] A new chiral azetidinone-carboxylate ligand for dirhodium(II) catalysis enhances reactivity toward diazo decomposition and selectivity toward cyclopropanation enabling diazomalonates, vinyldiazoacetates, and aryldiazoacetates to be effectively used with a dirhodium(II) carboxamidate catalyst.
