                                Enantio- and diastereoselective Michael addition reactions of α-cyanoketones to nitroalkenes catalyzed by binaphthyl-derived organocatalyst
                             
                            
                                摘要:
                                The catalytic enantioselective and diastereoselective Michael addition reactions promoted by chiral bifunctional organocatalysts are described. The treatment of alpha-cyanoketones with nitroalkenes under mild reaction conditions afforded the corresponding gamma-niro alpha-cyanoketones with excellent diastereoselectivities (up to syn/anti >99/1) and excellent enantioselectivities (up to 99% ee).
