Aqueous media carboxylative cyclization of propargylic amines with CO sub(2) catalyzed by amphiphilic dendritic N-heterocyclic carbene-gold(I) complexes

We prepared amphiphilic dendritic N-heterocyclic carbene (NHC)-gold(I) complexes having poly(ethylene glycol) units at the peripheral layer. By employing 1 mol % of the dendritic NHC-gold(I) catalyst, the aqueous media carboxylative cyclization of propargylic amines proceeded smoothly to provide the...

Zusammenfassung:We prepared amphiphilic dendritic N-heterocyclic carbene (NHC)-gold(I) complexes having poly(ethylene glycol) units at the peripheral layer. By employing 1 mol % of the dendritic NHC-gold(I) catalyst, the aqueous media carboxylative cyclization of propargylic amines proceeded smoothly to provide the corresponding 2-oxazolidinone under atmospheric pressure of CO sub(2) at room temperature.
