  通过伪卤化物中间体对脂肪族氟化物进行亲核取代

  摘要：

  已经报道了用多种亲核试剂将脂肪族氟化物官能化的方法。通过使用甲硅烷基化的假卤化物TMS-OMs或TMS-NTf 2热力学驱动碳-氟键裂解，导致形成TMS-F和捕获的脂族假卤化物中间体。氟化物/假卤化物的交换速率和该中间体的稳定性使得在直链脂肪族氟化物中几乎看不到末端氟化物的重排。将有机氟化物位置转化为假卤化物基团的能力允许各种亲核试剂容易地进行亲核攻击。亲核试剂的后期引入还允许偶联伴侣具有广泛的功能基团耐受性。在存在其他烷基卤化物的情况下观察到选择性的烷基氟化物甲磺酰化，从而允许正交合成策略。

• One-Pot Copper-Catalysed Thioetherification of Aryl Halides Using Alcohols and Lawesson's Reagent in Diglyme

  A new protocol for the thioetherification of structurally varied alcohols with aryl halides using Lawesson's reagent, catalysed by copper(I) iodide, and using diglyme as a safe solvent was developed. Using this method, the reactions of aryl halides proceeded efficiently, and the desired sulfides were obtained in high to excellent yields. The method uses alcohols as starting materials, which is a significant

  开发了一种使用 Lawesson 试剂、由碘化铜 (I) 催化并使用二甘醇二甲醚作为安全溶剂对结构不同的醇与芳基卤化物进行硫醚化的新方案。使用这种方法，芳基卤化物的反应可以有效地进行，并以高产率获得所需的硫化物。该方法使用醇作为起始材料，这比从硫醇开始的方法具有显着优势。与硫醇相比，醇在市场上广泛出售，其结构多样性要大得多，而且它们也无毒且无恶臭。提出了反应机理。

  Side effects from antipsychotic medications can have a profound effect on patients' lives and may adversely affect their willingness to comply with treatment. Identification of side effects through improved communication between psychiatrists, other members of the healthcare team, and their patients might increase treatment compliance. The Approaches to Schizophrenia Communication (ASC) Steering Group developed two simple, practical checklists for use in the busy clinical setting. The ASC–Self-Report (ASC-SR) checklist is completed by the patient and comprises a list of the more common or clinically important side effects of antipsychotic treatment. The ASC-Clinic (ASC-C) checklist is completed by both clinician and patient together, being used as the basis for a semi-structured interview. In a multicenter pilot study set up to evaluate the utility of checklists, 86% of patients responding considered the ASC-SR to be useful in communicating their problems to psychiatrists and other members of the healthcare team. All healthcare team respondents found both checklists to be helpful when discussing side effect problems with their patients. Moreover, 41% and 47% of healthcare team respondents reported that the ASC-SR and ASC-C, respectively, had assisted them in identifying side-effect problems not previously acknowledged. Preliminary evaluation of the ASC-SR and ASC-C in this multicenter pilot study suggests that both tools were user-friendly, encouraged communication between patients and healthcare professionals about antipsychotic drug side effects, and could readily integrated into everyday clinical practice.

  摘要抗精神病药物的副作用会对患者的生活产生深远的影响，并可能对他们遵从治疗的意愿产生不利影响。通过改善精神科医生、医疗团队其他成员和患者之间的沟通来识别副作用，可能会提高治疗依从性。精神分裂症沟通方法（ASC）指导小组开发了两份简单实用的核对表，可在繁忙的临床环境中使用。ASC-自我报告（ASC-SR）核对表由患者填写，包含一份抗精神病治疗中较为常见或临床上较为重要的副作用清单。ASC-临床（ASC-C）核对表由临床医生和患者共同完成，作为半结构化访谈的基础。在一项为评估核对表效用而设立的多中心试点研究中，86%的受访患者认为 ASC-SR 有助于向精神科医生和医疗团队的其他成员传达他们的问题。所有医疗团队的受访者都认为这两份核对表有助于他们与患者讨论副作用问题。此外，分别有 41% 和 47% 的医疗团队受访者表示，ASC-SR 和 ASC-C 有助于他们发现之前没有意识到的副作用问题。这项多中心试点研究对ASC-SR和ASC-C的初步评估表明，这两种工具对用户都很友好，能鼓励患者和医护人员就抗精神病药物的副作用进行交流，并能很容易地融入日常临床实践中。
