The iodines(III) have it: The rational design of a conformationally flexible C2‐symmetric iodosylarene catalyst has been used for the enantioselective Kita oxidative spirolactonization. The reaction occurs through secondary n–σ* or hydrogen‐bonding interactions between the chiral catalyst and the substrate. Mes=mesityl (2,4,6‐trimethylphenyl).
碘(III)具有:构象灵活的C 2对称碘亚芳烃催化剂的合理设计已用于对映选择性Kita氧化螺内酯化。该反应通过手性催化剂与底物之间的次级n–σ *或氢键相互作用而发生。Mes = mesityl(2,4,6-三甲基苯基)。
