    名称:
    Transacetalization of Diethyl Tartrate with Acetals of .alpha.-Dicarbonyl Compounds: A Simple Access to a New Class of C2-Symmetric Auxiliaries and Ligands
    摘要:
    A simple access to a new class of C-2-symmetric auxiliaries and ligands is based on the transacetalization of diethyl tartrate (1) with monoacetals of butane-2,3-dione in the key step. Acid-catalyzed reaction of 1 with 2 equiv of 3,3-diethoxybutan-2-one (2) gives the C-2-symmetric 1,4-dioxane 7 in 88% yield. Reduction of 7 with LiAlH4 affords the crystalline diol 9. The structure of 7 was established from the X-ray structure of 9. Dioxane 7 was converted by standard methodology into the diphosphine 24 and the TARTROL 22. Reaction of 1 with 3,3-dimethoxybutan-2-one (3) in the presence of BF3-etherate gives in analogy to the formation of 7 the 1,4-dioxane 8. This compound was transformed into the diphosphine 25 and the TARTROL 23. The trans-diaxial relationship of the methoxy groups present in 8 could be deduced without X-ray analysis from the H-1-NMR spectrum of 23.

  • Chiral <i>C</i><sub>2</sub>-Symmetric Ligands with 1,4-Dioxane Backbone Derived from Tartrates:  Syntheses and Applications in Asymmetric Hydrogenation

    日期:2002.11.1
    Chiral 1,4-diphenylphosphines 5-7 as well as thioether 8 were synthesized from tartrates employing Ley's "BDA" and "Dispoke" methodologies as the key step. Rhodium(I) complexes with 5-7 are efficient catalysts for the asymmetric hydrogenation of beta-substituted enamides and MOM-protected beta-hydroxyl enamides, which furnished chiral amines or beta-amino alcohols with 94-->99% ee. These results indicated
    手性1,4-二苯基膦5-7以及硫醚8是由酒石酸盐合成的,采用Ley的“ BDA”和“ Dispoke”方法作为关键步骤。含5-7的铑(I)配合物是有效的催化剂,可用于β-取代的酰胺和MOM保护的β-羟基酰胺的不对称加氢,从而提供了94-> 99%ee的手性胺或β-氨基醇。这些结果表明,具有一般结构2的配体中的1,4-二恶烷骨架在稳定金属-配体螯合物构象中起重要作用。与具有一般结构1的类似配体相比,配体2具有更高的对映选择性。
