  • Synthesis and Spectral Characteristics of 4<i>H</i>-1-Benzothiopyran-4-ones
    作者:Hiroyuki Nakazumi、Teijiro Kitao
    DOI:10.1246/bcsj.50.939
    日期:1977.4
    The physical properties of 4H-1-benzothiopyran-4-ones (thiochromones) and related compounds were characterized by means of mass, NMR, and UV spectra in order to distinguish thiochromones from 2H-1-benzothiopyran-2-ones (thiocoumarins). In the mass spectra, the fragmentation due to the retro-Diels-Alder reaction directly from the molecular ion is the most useful for differentiation. In the NMR spectra
    4H-1-benzothiopyran-4-ones(thiochromones)和相关化合物的物理性质通过质谱、NMR 和 UV 光谱进行表征,以区分 thiochromones 和 2H-1-benzothiopyran-2-ones(thiocoumarins)。在质谱图中,直接来自分子离子的 Retro-Diels-Alder 反应引起的碎片对区分最有用。在 NMR 光谱中,硫色酮显示出 5 位苯型质子的特征去屏蔽效应,在紫外光谱中,在 250-270 nm 区域显示出非常强的吸收带。发现在 S-苯基 3-硫代丁烷硫酸酯与 PPA 的反应中,这些化合物中的大多数通过重排得到硫色酮,得到中间体 (IVa)。

    This report focuses on the remote control of anion-π catalysis by electric fields. We have synthesized and immobilized anion-π catalysts to explore the addition reaction of malonic acid half thioesters to enolate acceptors on conductive indium tin oxide surfaces. Exposed to increasing electric fields, anion-π catalysts show an increase in activity and an inversion of selectivity. These changes originate
    本报告重点介绍电场对阴离子-π 催化的远程控制。我们合成并固定了阴离子-π 催化剂,以探索丙二酸半硫酯与导电氧化铟锡表面上的烯醇化受体的加成反应。暴露于不断增加的电场,阴离子-π 催化剂表现出活性增加和选择性反转。这些变化源于不受欢迎的烯醇加成反应的 100 倍以上的速率增强,同时过渡态识别的选择性增加了高达 -14.8 kJ mol-1。添加具有强 π 亲和力的硝酸盐使阴离子-π 催化剂对电场的响应性无效(IC50 = 2.2 mM)。

    S-Phenyl 3-oxobutanethioates,precursor for preparation of thiocoumarins, were prepared from benzenethiols and diketene in the presence of triethylamine. Cyclization of these compounds with PPA gave thiocoumarin and/or isomeric thiochromone derivatives.

  • Selective Catalytic Transesterification, Transthiolesterification, and Protection of Carbonyl Compounds over Natural Kaolinitic Clay
    作者:Datta E. Ponde、Vishnu H. Deshpande、Vivek J. Bulbule、Arumugam Sudalai、Anil S.Gajare
    DOI:10.1021/jo971404l
    日期:1998.2.1
    Transesterification and transthiolesterification of beta-keto esters with variety of alcohols and thiols and selective protection of carbonyl functions with various protecting groups catalyzed by natural kaolinitic clay are described. The clay has been found to be an efficient catalyst in transesterifying long chain alcohols, unsaturated alcohols, and phenols to give their corresponding beta-keto esters in high yields. For the first time, transthiolesterification of beta-keto esters with a variety of thiols has been achieved under catalytic conditions. Clay also catalyzes selective transesterification of beta-keto esters by primary alcohols in the presence of secondary and tertiary alcohols giving corresponding beta-keto esters. A systematic study involving the reactivity of different nucleophiles (alcohols, amines, and thiols) toward beta-keto esters is also described. Sterically hindered carbonyl groups as well as alpha,beta-unsaturated carbonyl groups underwent protection without the deconjugation of the double bond. Chemoselective protection of aldehydes in the presence of ketones has also been achieved over natural kaolinitic clay.
