By developing gem-difluoromethylene allenes as viable partners,regiocontrolled Rh(Ⅲ)-catalyzed redoxneutral C-C coupling/C-N cyclization has been realized to build the pyridin-2(1H)-one motifs with the embedment of a...
Very recently, we[1] found that L-proline amides and dipeptides acted as efficient catalysts for the asymmetric direct aldol reaction. We report here that L-proline-based peptides 1~5 can catalyze the aldol reactions ...
