A mild reaction sequence begins by transforming an alpha-hydroxy ester to an alpha-benzoate ester. Next, the alpha-benzoate ester is both reductively deoxygenated with samarium diiodide and subsequently condensed with a ketone present in the reaction mixture to afford a beta-hydroxy ester with two new alkyl appendages.
