    摘要:
    在3位上被烷基和氨基甲酰基单取代的β-硫内酯通过涉及S N的过程被芳硫醇盐进行亲核开环在4位上发生2型攻击,导致在3位上取代了3-芳基硫代丙酸酯。这些硫代羧酸盐可以通过亲山芳烃取代过程由Mukaiyama试剂或Sanger试剂原位捕获,从而导致高度活化的硫酯,然后使它们与伯胺或仲胺进一步反应,总体上导致一锅,三组分合成在2-位带有各种取代基的3-芳基硫代丙酰胺。或者,可用2,4-二硝基苯磺酰胺代替电子不足的芳基卤化物和胺的捕集组合,导致整体形成相同的产物,同时在磺酰胺中掺入潜伏胺到最终的酰胺产物中。在另一个实施例中,N-芳烃磺酰基3-芳基硫代丙酰胺衍生物。

    Both the alpha-protons and carbons of beta-propiothiolactones exhibit atypical downfield chemical shifts. The alpha-protons of beta-propiothioiactones with no heteroatom at the alpha-position appear at 3.53-5.35 ppm, whereas the alpha-carbons appear at 56.9-86.2 ppm. The major cause of the unexpected deshielding effect was rationalized by assuming a through-space interaction between the occupied orbital of the alpha-carbon and the vacant orbital of sulfur, Copyright (C) 2000 John Wiley & Sons, Ltd.
