  Stereoselectivity in the Wittig Reaction of Aromatic Ketones: Origin of Preference for the Olefin Geometry

  摘要：

  Investigation of the stereoselectivity observed in the Wittig reaction of aromatic ketones with ''nonstabilized'' phosphonium ylides revealed that the nature of the substituent on the phenyl ring of phenyl S-pyridyl ketone determined the stereoselectivity. Generally the Wittig reaction of such ketones with carboxy phosphonium ylides proceeded preferentially to yield (Z)-olefin, albeit with modest selectivity. However, the reaction with aryl sulfonamido-substituted aromatic ketones resulted in high (E)-stereoselectivity. In order to understand the origin of this high (E)-selectivity, a semiempirical conformational analysis of the four uncharged diastereomeric oxaphosphetane intermediates was performed with a cumulatively modified sampling procedure to generate initial conformations, followed by full energy optimization. Computational studies of the unsubstituted and 4-nitrophenyl-substituted oxaphosphetane intermediates were consistent with the low (Z)stereoselectivity observed. The results in the calculations of the aryl sulfonamido-substituted intermediate likewise were consistent with the high (E)-stereoselectivity observed. Calculations of the potassium-coordinated acid anion of the latter species were also performed. All calculations supported interaction of the sulfonamido and carboxylate groups by either hydrogen bonding or salt bridge formation which appears to effect the final stereochemical outcome. Furthermore, we investigated the stereoselectivity of Wittig reactions in which the sulfonamido NH or the carboxylate were removed. In both cases, the (Z)-olefin was formed preferentially, thereby supporting the existence of intramolecular hydrogen bonding or salt bridge formation.

  Ionic Liquid-Supported Synthesis of Sulfonamides and Carboxamides

  摘要：

  An ionic liquid-supported aldehyde was designed and converted to ionic liquid-supported secondary aryl amines through reductive amination. The reaction of ionic liquid-supported aryl amines with sulfonyl chlorides and acid chlorides, respectively, followed by cleavage using trifluoroacetic acid (TFA) afforded sulfonamides and caboxamides. To introduce additional diversity in the synthesis of sulfonamides and caboxamides, ionic liquid-supported iodosubstituted aryl amine was synthesized using the same strategy, and underwent Suzuki coupling reaction, followed by reaction with a methanesulfonyl chloride to generate the corresponding biaryl sulfonamide. The advantages of the protocol over solid-phase synthesis are homogeneous reaction medium, high loading, easy separation of products, and characterization of intermediates.

  A one-pot three-component reaction involving nitroarenes, (hetero)arylboronic acids, and potassium pyrosulfite leading to sulfonamides was described. A broad range of sulfonamides bearing different reactive functional groups were obtained in good to excellent yields through sequential C-S and S-N coupling that does not require metal catalysts.

  β-lactamase inhibitors and today several β-lactamase inhibitors e.g. avibactam, are approved in the clinic. Our focus is the oxacillinase-48 (OXA-48), an enzyme reported to spread rapidly across the world and commonly identified in Escherichia coli and Klebsiella pneumoniae. To guide inhibitor design, we used diversely substituted 3-aryl and 3-heteroaryl benzoic acids to probe the active site of OXA-48

  当在医学界中治疗细菌感染时，β-内酰胺抗生素至关重要。然而，目前它们的效用受到β-内酰胺抗性的出现和扩散的威胁。对β-内酰胺抗生素最普遍的耐药机制是β-内酰胺酶的表达。克服由β-内酰胺酶引起的抗性的一种方法是开发β-内酰胺酶抑制剂，如今临床上已经批准了几种β-内酰胺酶抑制剂，例如阿维巴坦。我们的研究重点是oxacillinase-48（OXA-48），据报道该酶在世界范围内迅速传播，通常在大肠杆菌和肺炎克雷伯菌中得到鉴定。为了指导抑制剂的设计，我们使用了不同取代的3-芳基和3-杂芳基苯甲酸来探测OXA-48的活性位点，以进行有用的酶-抑制剂相互作用。在本研究中，合成了包含49个3-取代的苯甲酸衍生物的聚焦片段文库，并对其进行了生化表征。基于从33片段的酶复合物晶体学数据，片段可以被归类为R 1或R 2个可以通过总体结合构象相对于粘合剂到R的结合1和R 2亚胺培南的侧基。此外，发现了对未来抑
