  • Asymmetric Cycloaddition of β,γ-Unsaturated α-Ketoesters with Electron-Rich Alkenes Catalyzed by a Chiral Er(OTf)3/N,N′-Dioxide Complex: Highly Enantioselective Synthesis of 3,4-Dihydro-2 H-pyrans

    日期:2011.7.11
    The asymmetric inverse‐electron‐demand hetero‐Diels–Alder (HDA) reactions of β,γ‐unsaturated α‐ketoesters with electron‐rich alkenes were investigated, with an N,N′‐dioxide/erbium(III) complex employed as the catalyst. Quantitative conversion of the β,γ‐unsaturated α‐ketoesters and excellent enantioselectivities (up to >99 % ee) and diastereoselectivities (up to >99:1 d.r.) were observed for a broad
    研究了β,γ-不饱和α-酮酸酯与富电子烯烃的不对称逆电子需求杂Diels-Alder(HDA)反应,并使用N,N'-二氧化物/ er(III)络合物作为催化剂。通过使用0.5–0.05 mol%的底物,在各种底物上都观察到了β,γ-不饱和α-酮酸酯的定量转化以及出色的对映选择性(高达> 99%  ee)和非对映选择性(高达> 99:1 dr)。在温和的反应条件下负载催化剂。可以将反应放大到克级,得到相同的结果。此外,这是Er(OTf)3的首次应用不对称逆电子需求的HDA反应,它表现为一种有效的催化剂。此外,通过合成某些天然产物的关键中间体,证明了该方法的合成效用。

    日期:1998.9.18
    Valuable substrates for the synthesis of natural products, compounds 3 (R1 =alkyl, aryl, alkoxy; R2 , R3 =alkyl) are formed from β,γ-unsaturated α-keto esters 1 and vinyl ethers 2 by the title reaction [Eq. (1)]. Copper(II) bisoxazolines act as catalysts, and in many cases enantiomeric excesses higher than 99.5 % are achieved.

The potential of the reaction is demonstrated by the synthesis of optically active carbohydrates such as spiro-carbohydrates, an ethyl beta-D-mannoside tetraacetate, and acetal-protected C-2-branched carbohydrates. On the basis of X-ray crystallographic data and the absolute configuration of the products, it is proposed that the alkene
