    摘要:
    已经开发了具有解离作用(甲基和另一个基团)的C 1和C 2不对称环状碳酸酯的对映选择性微生物水解。假单胞菌(FU)(Pseudomonas diminuta)(FU0090)可有效催化五元环状碳酸酯的水解。当反式底物以低对映体选择性和/或反应性水解时,微生物水解具有很高对映体选择性的顺式底物以提供相应的几乎光学纯的抗-(2 R,3 S)-二醇。另一方面,六员反式尽管顺式底物的水解产生外消旋化合物,但对环碳酸酯被对映选择性地水解以提供相应的旋光性顺式-(2 R,4 R)-二醇。在所有情况下,该酶都优选(R)-对映体作为带有甲基的碳原子。

    摘要:
    TiCl 4介导的O-(烯丙基)甲硅烷基保护的醛的烯丙基烷烃加成中的1,3-不对称诱导的感觉与先前报道的0-苄基保护的类似物的反应相反(> 62; 90%选择性)与烯丙基三甲基硅烷(抗选择性90%)。交叉实验表明严格的分子内相关性,表明分子内烯丙基硅烷的添加如图所示。出人意料的是,从TiCl 4到SnCl 4的转换导致非对映选择性的逆转和分子间烯丙基转移机理。这种类型的α-手性β-甲硅烷氧基醛不太适合于立体选择性烯丙基化。

    Iodide-bound ruthenium–JOSIPHOS complexes catalyze the redox-neutral C–C coupling of primary alcohols 2a–2r with the gaseous allene (propadiene) 1a to form enantiomerically enriched homoallylic alcohols 3a–3r with complete atom efficiency. Using formic acid as the reductant, aldehydes dehydro-2a and dehydro-2c participate in reductive C–C coupling with allene to deliver adducts 3a and 3c with comparable

  • Addition of Allylindium Reagents to Aldehydes Substituted at C<sub>α</sub> or C<sub>β</sub> with Heteroatomic Functional Groups. Analysis of the Modulation in Diastereoselectivity Attainable in Aqueous, Organic, and Mixed Solvent Systems
    作者:Leo A. Paquette、Thomas M. Mitzel
    DOI:10.1021/ja953682c
    日期:1996.1.1
    The stereochemical course of indium-promoted allylations to alpha- and beta-oxy aldehydes has been investigated in solvents ranging from anhydrous THF to pure H2O. The free hydroxyl derivatives react with excellent diastereofacial control to give significantly heightened levels of syn-1,2-diols and anti-1,3-diols. Relative reactivities were determined in the alpha-series, and the hydroxy aldehyde proved to be the most reactive substrate. This reactivity ordering suggests that the selectivity stems from chelated intermediates. The rate acceleration observed in water can be heightened by initial acidification. Indeed, the indium-promoted allylation reaction mixtures become increasingly acidic on their own. Preliminary attention has been accorded to salt effects, and tetraethylammonium bromide was found to exhibit a positive synergistic effect on product distribution. Finally, mechanistic considerations are presented in order to allow for assessment of the status of these unprecedented developments at this stage of advancement of the field.
