  摘要：

  1-Lithio-1-(phenylthio)alkanes 与 2-(N-甲基苯胺基)-丙烯腈的加成： 轻松获得 3-(苯硫基)酮和 2-烯酮 描述了合成标题化合物的简单而多用途的策略。关键步骤是将 1-硫代-1-（苯硫基）烷烃加到 2-（N-甲基苯胺基）丙烯腈中，使烯醇阳离子等价物发生亲核的苯硫烷基化反应。加合物的烷基化和水解可得到 3-（苯硫基）酮，这些酮可以分离出来，或者无需进一步纯化，通过著名的氧化-消除过程转化为 2-烯酮。烯丙基衍生物也可以发生这些反应，因此可以用同样的方法制备同源的乙烯基化合物。在第一步中形成的 1-亚硫基氨基硝酸酯经高温分解后，通过环化反应可得到环丙酮的氨基硝酸酯。

  Rongalite® and base-promoted cleavage of disulfides and subsequent Michael addition to α,β-unsaturated ketones/esters: an odorless synthesis of β-sulfido carbonyl compounds

  摘要：

  A highly practical method to access beta-sulfido carbonyl compounds was developed, which could be conducted without any expensive reagent, special apparatus/technique, and no requirement of metal catalysts. beta-Sulfido carbonyl compounds were formed at room temperature, in short time and with high chemoselectivity in good to excellent yields. A plausible mechanism for the role of Rongalite (R), as a promoter for the cleavage of disuffides generating thiolate anions that then undergo facile thia-Michael addition to alpha,beta-unsaturated ketones and esters is proposed.

  The Addition of 1-Lithio-1-(phenylthio)alkanes to 2-(N-Methylanilino)-acrylonitrile: An Easy Access to 3-(Phenylthio)ketones and 2-Enones A simple and versatile strategy for the synthesis of the title compounds is described. The key-step consists in the addition of 1-lithio-1-(phenylthio)alkanes to 2-(N-methylanilino)acrylonitrile, the nucleophilic phenylthioalkylation of an enol-cation equivalent. Alkylation of the adducts and hydrolysis give 3-(phenylthio)ketones, which can be isolated, or without further purification can be transformed into 2-enones via the wellknown oxidation-elimination procedure. These reactions are possible with allylic derivatives too, therefore the homologous vinylic compounds can be prepared by the same way. Pyrolysis of the 1-lithioaminonitriles formed within the first step gives aminonitriles of cyclopropanones via cyclization.
