In this report, the desymmetrization of cyclic enones under relay Heck conditions with an array of aryl boronic acids, alkenyl triflates and indole derivatives is described. This method grants facile access to diverse γ‐functionalized cyclopentenones and δ‐functionalized cycloheptenones. Using this approach, a formal synthesis of (S)‐baclofen was completed in high yield and excellent enantioselectivity
在该报告中,描述了在中继赫克条件下用一系列芳基硼酸,烯基三氟甲磺酸酯和吲哚衍生物对环状烯酮的脱对称。这种方法可以轻松地获得各种γ-官能化的环戊烯酮和δ-官能化的环庚烯酮。使用这种方法,以高收率和优异的对映选择性完成了(S)-baclofen的正式合成。
