AbstractA series of chiral N-heterocyclic carbenes (NHCs), derived from L-pyrOgutamic acid, were found to be efficient catalysts for the asymmetric dirnerization of alkylarylketenes to give the corresponding alpha-quaternary beta-alkylidenyl-beta-lactones in good yields with up to 97% ee. A chiral NHC with a proximal hydroxy group is superior in comparison with the corresponding NHC with its hydroxy group protected.
