Michael addition of nitroalkanes to 2-phenylsulfonyl 1,3-dienes proceeded smoothly in the presence of DBU to give nitrosulfones (e.g. 2) in high yield. Transformation of the nitro group of the adduct to a keto function (Nef type reaction) and subsequent elimination of benzenesulfinic acid afforded conjugated dienones and dienals with high stereoselectivity.
