The novel tris(triphenylphosphine)rhodium chloride/boron trifuoride etherate [RhCl(PPh3)3/BF3⋅OEt2] co-promoted the CC cross-coupling of tertiary alcohols at the β-position with aldehydes. This reaction provides an efficient synthesis of either structurally diverse 1,3-diols or polysubstituted tetrahydropyrans by controlling the substrate structures, and it could be developed to a practical synthetic
新颖的三(三苯基膦)氯化铑/硼合乙醚trifuoride [的RhCl(PPH 3)3 / BF 3 ⋅OEt 2 ]共同促进的CC在β叔醇的交叉偶联-与醛位置。通过控制底物结构,该反应可提供结构多样的1,3-二醇或多取代的四氢吡喃的有效合成方法,并且可将其开发为多种天然产物和重要医学化合物的实用合成方法。
