    Answer

    nuc add synth a1.png

    A Wittig reaction can convert the ketone into the alkene while adding two carbons. Hydroboration oxidation will oxidize the less substituted end of the alkene to an alcohol. Finally chromium oxidation with either chromic acid or pyridinium chlorochromate will oxidize the alcohol to the product ketone.
