    摘要:
    为了研究分子结构对巯基链烷醇的感官特性的影响,同源系列的1-巯基烷-3-醇,3-巯基烷-1-醇,2-巯基烷-1-醇,4-巯基烷-2-醇,3合成了-巯基-3-甲基烷烃-1-醇,1-巯基-2-甲基烷烃-3-醇,3-巯基-2-甲基烷烃-1-醇和2-乙基-3-巯基烷烃-1-醇。确定空气和气味质量的气味阈值,并将获得的结果与化学结构相关。感官特性受空间效应的强烈影响:所有同源序列均显示,在五个至七个碳原子之间的气味阈值最小,并且碳链长度的增加导致气味阈值呈指数增加。硫醇的嗅觉能力通过在硫醇基团的α位上的甲基或乙基取代以及在含巯基的碳原子上的另外的甲基或乙基而大大改善了。通过比较分子相似指数分析,可以建立3D-定量构效关系模型,该模型能够预测巯基链烷醇的气味阈值,与实验结果吻合良好。提供了49种巯基链烷醇的保留指数,NMR数据和质谱图,其中大多数是首次合成制备。能够预测巯基链烷醇的气味阈值,与实验结果

    Matching catalyst and substrate: Organocatalytic cycloaddition between dienamines and 1,4‐benzo‐ or 1,4‐naphthoquinones affords biologically interesting dihydronaphtho‐ and dihydroanthraquinone core structures. The enantioselectivity of this new reaction is ensured by a steric shielding catalyst and carefully selecting substrates that greatly favor the endo approach (see scheme) due to electrostatic

    Asymmetric α,γ-regioselective [3 + 3] formal cycloadditions of α,β-unsaturated aldehydes and 2-nitroallylic acetates have been developed for the first time. These reactions proceeded through a domino Michael addition–Michael addition sequence via an unusual cascade dienamine–dienamine catalysis of a chiral secondary amine, and multifunctional cyclohexene derivatives were generally constructed in moderate

  • How Cysteine Reacts with Citral:  An Unexpected Reaction of β,β-Disubstituted Acroleins with Cysteine Leading to Hexahydro-1,4-thiazepines
    作者:Christian Starkenmann、Robert Brauchli、Bruno Maurer
    DOI:10.1021/jf051712h
    日期:2005.11.1
    citral (3)] with cysteine gave 1:2 adducts of a novel structural type, namely hexahydro-1,4-thiazepines. To the best of our knowledge, the spontaneous formation of a seven-membered heterocycle from the addition of cysteine to alpha,beta-unsaturated aldehydes is unprecedented. The adduct 6 obtained from citral, under acidic conditions, reacted further to give the new bicyclic compound 8.
