• Formation of Quaternary Carbon Centers by Highly Regioselective Hydroformylation with Catalytic Amounts of a Reversibly Bound Directing Group

  Directly opposing Keulemans rule! Phosphinites work as reversibly bound directing groups allowing for the first highly regioselective hydroformylation of 3‐substituted homoallylic alcohols to construct quaternary carbon centers. This method enables the atom‐economical synthesis of a wide range of α,α‐disubstituted γ‐lactones and highly substituted tetrahydrofurans (see scheme; R1, R2=alkyl/aryl).

  直接反对Keulemans统治！次膦酸盐作为可逆结合的导向基团起作用，从而允许3-取代均烯丙基醇的首次高度区域选择性加氢甲酰化以构建季碳中心。该方法可实现多种α，α-二取代的γ-内酯和高度取代的四氢呋喃的原子经济合成（参见方案； R 1，R 2 =烷基/芳基）。
