A highlyenantioselectiveorganocatalytic protocol for conjugateaddition of new nucleophilic carbonylmethyl 2-pyridinylsulfone to enals has been developed in good yields and with high enantioselectivities. The resulting Michael adducts are versatile building blocks for a variety of organic transformations.
