A facile synthesis of various substituted α,β-unsaturated ketones utilizing nitroalkenes and sulfones are described, in which conjugate addition of sulfonyl carbanions to nitroalkenes, ozonolysis or acid treatment of the resulting lithium nitronates, and subsequent elimination of sulfinic acid from keto sulfones by DBU are involved.
