  Methadone is safe for treating hospitalized patients with severe pain

  摘要：

  Purpose: Methadone is still regarded as a second line opioid for patients suffering from severe pain, and is rarely used in hospitalized patients. The infrequent use of methadone is probably due to its long plasma half-life that could lead to accumulation and toxicity. In the present study we report that clinically effective analgesic doses of methadone, given either epidurally or orally, can be used safely for prolonged treatment in hospitalized patients.Clinical features: Over a five-year period we administered methadone at Hadassah Hospital in Jerusalem to 3,954 in-patients with severe pain, 12% of whom were younger than 17 yr. Satisfactory pain relief was recorded in more than 85% of the patients. None of the patients treated with oral methadone developed serious side effects. Three patients, treated with epidural methadone (0.09%), developed a clinically significant respiratory depression, In all three cases, epidural pump failure or pump misprogramming resulted in methadone overdose, None of the children or adults treated with methadone developed addiction during hospitalization.Conclusion: Based on its analgesic properties and marked safety profile, we suggest that methadone could be added to the analgesic armamentarium of in-hospital health-care providers. Moreover, methadone could serve as the opioid of first choice in some inpatient populations.

  Synthesis of synthons: The asymmetric hydrogenation and subsequent in situ lactonization with Ru-diphosphines results in the direct conversion of a series of 2-acylarylcarboxylates including 2-aroylarylcarboxylates into the corresponding optically active 3-substituted phthalides under mild reaction conditions.

  diversely substituted 2-aroylbenzoate esters featuring a new protocol for the carbonylative coupling of aryl bromides with boronic acids and a new strategy to favour carbonylative over non-carbonylative reactions. Two different synthetic pathways - (i) the alkoxycarbonylation of 2-bromo benzophenones and (ii) the carbonylative Suzuki-Miyaura coupling of 2-bromobenzoate esters - were evaluated. The latter approach

  我们已经开发出一种羰基化方法，用于合成不同取代的2-芳基苯甲酸酯，其特征是芳基溴化物与硼酸进行羰基化偶联的新方案，以及采用羰基化而非非羰基化反应的新策略。评估了两种不同的合成途径-（i）2-溴二苯甲酮的烷氧基羰基化和（ii）2-溴苯甲酸酯的羰基化Suzuki-Miyaura偶联-。后一种方法提供了更宽的基材耐受性，因此是首选途径。我们观察到2-取代的芳基溴化物是具有挑战性的羰基化化学底物，有利于非羰基化途径。但是，我们发现，缓慢添加硼酸可以改善羰基化的Suzuki-Miyaura偶联，

  3‐disubstituted phthalides in good to high yields at ambient temperature. In a similar manner, 3‐hydroxyisoindolin‐1‐one and 3‐hydroxyoxindole derivatives could also be easily prepared by direct reductive coupling of phthalimides and N‐substituted isatins with activated alkenes, respectively. Application of this methodology towards the synthesis of 1‐naphthol derivatives on a gram scale is also depicted

  据报道，一种有效的方法可以合成三类杂环衍生物，例如3,3-二取代的邻苯二甲酸酯，3-羟基异吲哚啉-1-酮和3-羟基羟吲哚。在简单的还原体系的存在下，锌（Zn）/氨（NH 3）[或锌铜（Zn-Cu）/氨），包括丙烯酸酯，丙烯腈，丙烯酰胺和乙烯基亚砜在内的各种烯烃都经历了还原偶联与2酰基苯甲酸甲酯和随后的内酯​​化反应可在环境温度下以良好或高收率提供3,3-二取代的邻苯二甲酸酯。以类似的方式，也可以通过邻苯二甲酰亚胺和N的直接还原偶联轻松制备3-羟基异吲哚啉-1-酮和3-羟基羟吲哚衍生物分别用活化的烯烃预取代的isatins。还描述了该方法在1克级合成1-萘酚衍生物中的应用。此外，分子内邻苯二甲酰亚胺-烯的还原偶联提供了具有高非对映选择性的各个环化产物。

  zed carbonylations involved either toxic carbon monoxide (CO) gas as carbonylating agent or functional-group-assisted ortho sp2 C–H activation (i.e., ortho acylation) or carbonylation by activation of the carbonyl group (i.e., via the formation of enamines). Contradicting these methods, here we describe an environmentally benign process, [Pd]-catalyzed direct carbonylation starting from simple and

  最近的研究趋势已趋向于开发使用无毒试剂的有效策略。较早报道的过渡金属催化的羰基化涉及有毒的一氧化碳（CO）气体作为羰基化剂或官能团辅助的邻位sp 2C–H活化（即邻位酰化）或通过羰基活化（即通过形成烯胺）进行羰基化。与这些方法相反，在此我们描述了一种环境友好的过程，即[Pd]催化的直接羰基化反应，该反应从简单的可商购的碘代芳烃和醛开始，用于合成多种酮。此外，该方法包括使碘代芳烃与醛直接偶联而不活化羰基，也无需直接进行基团辅助。重要的是，该策略已成功地应用于合成正丁基邻苯二甲酸酯和匹托芬酮。

  An interesting type of reaction involving functionalized methylenecyclopropanes (MCPs) has been revealed. Here, a nucleophilic attack of an anionic species onto a partially polarity-reversed MCP was realized by treating a neighbouring carboxylic ester tethered to the MCP and amine with KHMDS to realize an umpolung ring opening of the MCP. This work established an operationally convenient protocol for
