  钯催化酰化：一锅法合成酞嗪、酞嗪酮和苯并恶嗪酮

  摘要：

  提出了一种用于酞嗪、酞嗪酮和苯并恶嗪酮多样化合成的连续单锅策略。该策略通过 [Pd] 催化的酰化和与双亲核试剂的亲核环缩合反应进行。该过程基于与简单的台式醛直接偶联，没有导向基团的帮助，也没有活化羰基。该方法非常有利，因为它使用简单的氮基亲核试剂和无毒且易于获得的醛作为羰基来源。最重要的是，该策略被应用于 PDE-4 抑制剂的一锅合成。

  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.

  anthraquinones via one-pot relay process, is presented. The first acylation was feasible under [Pd]-catalyzed intermolecular direct acylation reaction, while, the second acylation was accomplished by using intramolecular Friedel–Crafts acylation. Notably, benchtop aldehydes have been utilized as non-toxic acylation agents in the key [Pd]-catalyzed acylation. A bis-acylation strategy to access functionalized anthraquinones

  摘要 提出了一种双酰化策略，可通过一锅接力过程获得功能化的蒽醌。在[Pd]催化的分子间直接酰化反应下，第一次酰化是可行的，而第二次酰化是通过使用分子内Friedel-Crafts酰化来完成的。值得注意的是，台式醛已在关键的[Pd]催化的酰化反应中用作无毒的酰化剂。 提出了一种双酰化策略，可通过一锅接力过程获得功能化的蒽醌。在[Pd]催化的分子间直接酰化反应下，第一次酰化是可行的，而第二次酰化是通过使用分子内Friedel-Crafts酰化来完成的。值得注意的是，台式醛已在关键的[Pd]催化的酰化反应中用作无毒的酰化剂。

  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。
• Construction of an isoquinolinone framework from carboxylic-ester-directed umpolung ring opening of methylenecyclopropanes

  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

• Synthesis of Fluorenone and Anthraquinone Derivatives from Aryl- and Aroyl-Substituted Propiolates
  作者：Florian Pünner、Justin Schieven、Gerhard Hilt

  DOI：10.1021/ol4023276

  日期：2013.9.20

  Fluorenone derivatives were generated from aryl-substituted propiolates via a cobalt-catalyzed Diels-Alder reaction/DDQ-oxidation and Friedel-Crafts-type cyclization. Several functional groups are tolerated, and good to excellent overall yields (up to 89%) could be achieved. For the synthesis of anthraquinone derivatives, aroyl-substituted propiolates were applied in a zinc iodide catalyzed Die Is Alder reaction with 1,3-dienes. The subsequent DDQ oxidation and Friedel-Crafts-type cyclization led to symmetrical as well as some unsymmetrical anthraquinones in good to excellent yields of up to 87% over the three-step reaction sequence.
• Novel antiasthmatic agents with dual activities of thromboxane A2 synthetase inhibition and bronchodilation. 1. 2-[2-(1-Imidazolyl)alkyl]-1(2H)-phthalazinones

  A number of 4-substituted 2-[omega-(1-imidazolyl)allryl]-1(2H)-phthalazinones were synthesized in order to develop agents possessing both thromboxane Az synthetase inhibitory and bronchodilatory activities. The pharmacological evaluation of these compounds disclosed that they have both activities to various extents. Both activities were slightly dependent on the length of the 2-substituents and largely affected by the nature of the 4-substituents. Compounds bearing phenyl and thienyl groups exhibited relatively high and well-rounded activities. Among these compounds, 12j and 15f were found to be the most effective agents having well-rounded activities in vitro and in vivo. Introduction of a carboxyl group reduced both activities contrary to our expectation. 4-(3-Pyridyl)phthalazinone 18b was of particular interest because of unexpectedly high in vivo activities in spite of an absence of significant in vitro activities.
