  • Synthesis and evaluation of 7-hydroxyindan-1-one-derived chiral auxiliaries
    作者:Arun A Narine、Peter D Wilson
    DOI:10.1139/v05-052
    日期:2005.5.1

    A series of novel chiral acetals were prepared from 7-hydroxyindan-1-one and a variety of substituted chiral nonracemic C2-symmetric 1,2-ethanediols (R = Me, Ph, CH2OMe, CH2OBn, CH2O(1-Np), and i-Pr). These acetals were evaluated as chiral auxiliaries for use in asymmetric synthesis. A high degree of stereochemical induction was observed in the diethylaluminum chloride-promoted Diels–Alder reaction of an acrylate derivative (R = i-Pr) with cyclopentadiene (91:9 dr). This demonstrated that these acetals could serve as effective chiral directors in asymmetric substrate-directed reactions.Key words: 7-hydroxyindan-1-one, chiral nonracemic C2-symmetric 1,2-diols, acetals, chiral auxiliaries, Diels–Alder reaction.

    for the stereoselective synthesis of highly substituted α,β‐unsaturated δ‐hydroxy carboxyl acids, structural motifs widespread found in polyketide natural products. The protocol is rather flexible and permits the introduction of substituents and functionalities also at those positions which are not accessible by the commonly used aldol reaction. Therefore, this ester dienolate Matteson approach is an
    在 Matteson 同系物中应用酯二烯醇盐作为亲核试剂,可以立体选择性合成高度取代的 α,β-不饱和 δ-羟基羧酸,这是聚酮化合物天然产物中广泛存在的结构基序。该方案相当灵活,并且允许在常用羟醛反应无法到达的位置引入取代基和官能团。因此,这种酯二烯醇化物 Matteson 方法是“经典”聚酮化合物合成的一个有趣的替代方案。

Moreover, it was observed that the complex of the bipyridyl ligand (R = Ph) and copper(I) chloride

    日期:1986.1
    (S,S)-Diisopropylethanediol, “DIPED”, has been synthesized by means of our new general chiral diol synthesis based on α-chloro boronic esters, and has in turn been shown to be an effective chiral (R) directing group in this synthesis, consistently yielding (R)/(S)-ratios in the 25:1 to 30:1 range with a series of typical substrates.
