  Divergent Reactivity in the Reaction of β-Oxodithioesters and Hydroxylamine: Access to β-Ketonitriles and Isoxazoles

  摘要：

  Starting from beta-oxodithioesters and hydroxylamine, two completely different transformations afford either beta-ketonitriles or isoxazoles with high chemoselectivity depending on the reaction conditions. The reaction of beta-oxodithioesters with hydroxylamine in EtOH at room temperature in daylight gave beta-ketonitriles in high yields. On the other hand, 3-methylthio-isoxazoles were efficiently obtained as the final products by heating the mixture of beta-oxodithioesters and hydroxylamine in HOAc at 90 degrees C.

  Highly convergent and regioselective approach to hitherto unreported and synthetically demanding 6-cycloamino-2-(methyl/benzyl)sulfanyl-3-(aroyl/hetaroyl/alkanoyl)-4-aryl-5,6-dihydro-4H-thiopyrans has been developed via one-pot three-component domino coupling of β-oxodithioesters, α,β-unsaturated aldehydes, and cyclic aliphatic secondary amines at room temperature under catalyst-free and solvent-free

  高度会聚和区域选择性的方法来迄今未报告的和合成苛刻6-环氨基-2-（甲基/苯甲基）硫烷基-3-（芳酰基/杂芳酰基/链烷酰基）-4-芳基-5,6-二氢-4- ħ -thiopyrans一直通过在无催化剂和无溶剂条件下于室温下通过一锅三组分的β-氧二硫代酯，α，β-不饱和醛和环状脂族仲胺的多米诺偶联反应开发。该策略的吸引人的特征包括条件温和，反应时间短，原子经济性高，产率高以及在单个冲程中形成三个新键（C–C，C–N和C–S）和一个环的功效。

  operationally simple, mild, and catalyst‐free one‐pot protocol to access privileged pyrazoles and disulfide‐tethered pyrazoles has been devised by [3+2] heteroannulation of β‐ketodithioesters with semicarbazide hydrochloride in water under open air. The pH of the medium played a key role toward the selectivity switch, as refluxing in water led to the formation of pyrazoles, whereas addition of sodium acetate

  通过[3 + 2]将β-酮基二硫代酯与氨基脲在水中在露天条件下[3 + 2]异环化反应，已设计出一种操作简单，温和且无催化剂的单罐方案，可访问特权吡唑和二硫键联吡唑。介质的pH值对选择性的转换起着关键作用，因为在水中的回流导致吡唑的形成，而在水中加入乙酸钠则可以形成二硫键连接的吡唑。值得注意的是，该方案涉及胺化/环化/脱水/加氢脱硫/水解/脱酰胺反应的串联序列。概述了该区域/化学选择性多米诺反应的机理原理，该原理得到密度泛函理论计算的充分支持和验证。

  The unique properties of ketoximes are used prominently for the synthesis of heterocycles. In contrast, their potential to absorb light and photoelectron transfer processes remains challenging. Widespread interest in controlling direct excitation of ketoxime tacticity unlocks unconventional reaction pathways, enabling photochemical intramolecular skeletal modification to constitute alkynyl sulfides

  酮肟的独特性质主要用于杂环的合成。相反，它们吸收光和光电子转移过程的潜力仍然具有挑战性。控制酮肟策略的直接激发的广泛兴趣开辟了非常规的反应途径，从而使光化学分子内骨架修饰能够构成炔烃硫化物，而传统的活化是无法实现的。尽管取得了数十年的进步，但炔烃硫化物，特别是那些由极性官能团组成并衍生自可再生资源的硫化物，仍然未知。这些发现证明了从β-氧代二硫代酯中还原的酮肟对于确定反应条件的重要性。该方法使用温和的反应条件来生成激发态光还原剂，以使炔基硫醚阵列功能化。此外，使用电化学和光谱技术/实验对基本步骤的基本理解揭示了PCET途径可以实现这种转化，而所涉及的底物及其性能以及改进的经济工具则表明了该方法的翻译潜力。

• Visible-Light Photocatalysis of Eosin Y: HAT and Complementing MS-CPET Strategy to Trifluoromethylation of β-Ketodithioesters with Langlois’ Reagent
  作者：Sonam Soni、Pragya Pali、Monish Arbaz Ansari、Maya Shankar Singh

  DOI：10.1021/acs.joc.0c01355

  日期：2020.8.7

  A metal- and oxidant-free photoinduced strategy for thioxo sulfur-selective trifluoromethylation of beta-ketodithioesters at room temperature is reported. Excellent Z/E-stereoselectivity has been achieved with cheap and viable Langlois' reagent (CF3SO2Na, sodium triflinate) in the presence of eosin Y, which acts as a hydrogen atom transfer (HAT) catalyst. The reaction proceeds via disulfide intermediate disulfanediylbis(3-(alkylthio)-1-phenylprop-2-en-1-one) (a dimer of beta-ketodithioester) followed by complementing proton-coupled electron transfer-mediated reverse HAT cycle of eosin Y. This operationally simple and efficient protocol allows direct access to triflinated alpha-oxoketene dithioacetals in good to excellent yields bearing diverse synthetically useful functional groups of different electronic and steric nature.
