  Palladium Catalyzed Oxidative Coupling of α-Enolic Dithioesters: A New Entry to 3,4,5-Trisubstituted 1,2-Dithioles via a Double Activation Strategy

  摘要：

  An operationally simple, facile, and convenient one-pot straightforward method for the construction of 3,4,5-trisubstituted 1,2-dithioles has been explored and developed via palladium catalyzed self-coupling of alpha-enolic dithioesters for the first time. Pd(0) efficiently catalyzes the activation and cleavage of S-H and C-S bonds to achieve cascade coupling, which results in the concomitant formation of new S-S and C-C bonds. Optimization data, substrate scope, and mechanistic insights are discussed.

  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, straightforward, and highly chemoselective strategy has been devised for the synthesis of a broad range of indeno[1,2-b]thiophenes through the annulation of α-enolic dithioesters with ninhydrin under solvent-free conditions. The advantages of this nucleophilic domino substitution/cyclization sequence are highlighted by the use of inexpensive and readily available FeCl3·6H2O as the catalyst

  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。

  An efficient, sustainable, and regioselective one-pot synthesis of hitherto unreported 4-aroyl/hetaroyl/alkanoyl-5-alkyl/allyl/benzylsulfanyl-1,2,3-thiadiazoles has been achieved by [3 + 2] cycloaddition of α-enolicdithioesters with tosyl azide through cascade 1–2 (S–N) and 3–4 (C–N) bond connections involving Wolff-type heterocyclization. Optimally, the reactions are very fast and completed within 2–15 minutes, when a mixture of α-enolicdithioester and tosyl azide was stirred at 0 °C in the presence of Et3N under solvent-free conditions. Furthermore, no co-catalyst or activator is necessary. The eco-compatibility, mild conditions, excellent yields, easy purification, and avoidance of expensive/toxic reagents are advantages of this protocol to access this medicinally privileged substructure.
