  Easy access to α-hydroxyimino-β-oxodithioesters and application towards the synthesis of diverse 1,4-thiazine-3-ones via reduction/annulation cascade

  摘要：

  An operationally simple and facile synthesis of alpha-hydroxyimino-beta-oxodithioesters has been achieved by nitrosation of alpha-enolicdithioesters. They were further treated with internal alkynes to afford diverse 1,4-thiazin-3-ones via domino reduction/annulation strategy under mild reaction conditions. Importantly, this is the first straightforward entry to highly functionalized 1,4-thiazin-3-one derivatives from simple starting materials. (C) 2014 Elsevier Ltd. All rights reserved.

• Metal-Free One-Pot Four-Component Cascade Annulation in Ionic Liquids at Room Temperature: Convergent Access to Thiazoloquinolinone Derivatives

  An efficient, eco-friendly, and highly convergent one-pot route to privileged thiazoloquinolinone derivatives has been developed via four-component cascade coupling (4CCC) of α-enolic dithioesters, cysteamine/2-aminothiophenols, aldehydes, and cyclic 1,3-diketones in recyclable [EMIM][EtSO4] ionic liquid at room temperature for the first time. The reaction proceeds via a N,S-acetal formation, Knoevenagel

  通过α-烯醇二硫代酸酯，半胱胺/ 2-氨基硫代酚，醛和环状1,3-的四组分级联反应（4CCC），开发了一种高效，生态友好且高度收敛的一锅合成特权噻唑基喹啉酮衍生物的途径。室温下可循环使用的[EMIM] [EtSO 4 ]离子液体中的二酮首次出现。反应通过N，S进行-缩醛形成，Knoevenagel缩合，氮杂-烯反应，亚胺-烯胺/酮-烯醇互变异构和分子内N-环化级联序列。该协议的优点突出在于它可以形成连续的五个新键（两个C–C，两个C–N和一个C–S）和两个环，并有效利用所有反应物的功效。操作简便，可持续性，温和条件，优异的收率，宽泛的官能团耐受性以及避免使用昂贵/有毒的试剂是该多米诺骨牌四组分方案的其他属性。值得注意的是，产物易于与离子液体分离，因此获得的离子液体被重复使用四次而没有任何活性的显着损失。

  An efficient one‐pot allylic alkylation of α‐enolic dithioesters (DTEs) with Morita‐Baylis‐Hillman (MBH) acetates has been devised in ethanol at room temperature. The reaction being site‐selective provided S‐allylated product exclusively with trace amount of C‐allylated one. Remarkably, some of the S‐allylated product undergoes [3,3]‐sigmatropic rearrangement to C‐allylated one under ethanol reflux

  室温下在乙醇中设计了一种有效的一锅法烯醇二硫代酯（DTE）与Morita-Baylis-Hillman（MBH）乙酸酯的烯丙基烷基化反应。现场选择性反应只为S-烯丙基化产物提供痕量的C-烯丙基化产物。值得注意的是，一些S-烯丙基化的产物在乙醇回流下经历了[3,3]-σ重排，变成C-烯丙基化的产物。该方案的典型特征是分离出S-烯丙基化的α-氧杂环丁烯二硫缩醛（一种三取代的烯烃），该化合物已被进一步用于合成硫吡喃。

  We have reported an indium(0)-mediated C sp 3–S/O cross-coupling approach that leads to the highly regioselective alkylation of α-enolic acetate/dithioacetate systems. This hetero cross-coupling reaction does not require additional co-catalyst or promoter, and the in situ generated organoindium species promotes the reaction by acting as the coupling partner of the α-enolic acetate/dithioacetate substrates

  我们已经报道了一种铟（0）介导的 C sp 3-S/O 交叉偶联方法，该方法导致 α-烯醇乙酸酯/二硫代乙酸酯系统的高度区域选择性烷基化。这种杂交叉偶联反应不需要额外的助催化剂或促进剂，原位生成的有机铟物质通过充当 α-烯醇乙酸酯/二硫代乙酸酯底物的偶联伙伴来促进反应。C-、S- 或 O-烷基化的出色选择性完全取决于 α-烯醇乙酸酯/二硫代乙酸酯体系的亲核行为。这些结果得到了底物和产物的相对电子能量的 DFT 计算以及相应转换的激活势垒的进一步支持。

  A facile, cost-effective, and highly efficient copper-catalyzed, TEMPO-mediated straightforward synthesis of 2,3-disubstituted naphtho[2,1-b]thiophene-4,5-diones has been achieved via cross-dehydrogenative thienannulation. The reaction proceeded via in situ generated naphthalene-1,2-diones by dearomatization of β-naphthols, followed by oxidative heteroannulation with α-enolic dithioesters chemoselectively
