A silver/DBU catalyst system was developed for the effective synthesis of cyclic carbonate and oxazolidinone from the reaction of CO2 with propargylicalcohols and propargylic amines, respectively,...
The combined catalyst system of silver acetate with a chiral Schiff base ligand achieved asymmetric carbondioxideincorporation into bispropargylic alcohols with desymmetrization to afford the corresponding cyclic carbonates with good-to-excellent enantiomeric excesses.
