Chelation-Controlled 1,3-Asymmetric Induction in Radical Addition to γ-Hydroxy-and γ-Alkoxy-α-methylenecarboxylic Esters.

γ-Oxy-α-methylenecarboxylic esters react with the organic iodides (II) under radical conditions in the presence of mild Lewis acids. Isopropyl or cyclohexyl iodide give the syn-adducts (III) predominantly, whereas tert-butyl iodide affords the anti-adducts (IV) preferentially. -(NAGANO, HAJIME; TOI,
