  • An efficient preparation of optically active (E)-γ-hydroxy-α,β-unsaturated phenyl sulfones using lipase-mediated acylations
    作者:Esteban Domínguez、Juan Carlos Carretero、Alfonso Fernández-Mayoralas、Santiago Conde

  • Chlorofluoroacetic Acid as a Highly Versatile Derivatizing Agent: Assignment of Stereochemistry to Esters of Chiral Alcohols
    作者:Josef Růžička、Ludvík Streinz、David Šaman、Zdeněk Havlas、Zdeněk Wimmer、Marie Zarevúcka、Bohumír Koutek、Ladislav Lešetický

    Stereochemistry of a series of diastereomeric esters obtained from chiral alcohols 1a-21a by derivatization with (S)- or (R)-chlorofluoroacetic acid was correlated with their LC and GC separation (∆tr) and NMR resolution (∆δ). Both the chromatographic and NMR spectral behavior of respective diastereomers was found to follow systematic rules reflecting their steric arrangement. Moreover, identical conformations of the esters seem to be preferred in solution as well as in the chromatographic processes. Reasons underlying this behavior are discussed.

    一系列由手性醇1a-21a经过与(S)-或(R)-氯氟乙酸衍生而得到的对映异构的立体化学与它们的LC和GC分离(Δtr)以及NMR分辨率(Δδ)相关联。发现各对映异构体的色谱和NMR光谱行为均遵循反映它们空间排列的系统规律。此外,的相同构象似乎在溶液中以及色谱过程中更受青睐。讨论了导致这种行为的原因。

    sustainable and environmentally benign alternative to hazardous insecticides. 4-Methylheptan-3-ol is an interesting example of an insect pheromone, because its stereoisomers are active towards different species. All four possible stereoisomers of this compound were prepared from 4-methylhept-4-en-3-one by a one-pot procedure in which the two stereogenic centres were created during two sequential reductions
