制备方法与用途

化学性质：结晶，熔点为184℃。

用途：作为苯唑青霉素钠的中间体。

生产方法：通过在碱性条件下将苯甲醛与盐酸羟胺肟化生成苯甲肟，再用氯气氯化得到苯甲肟氯。后者在碱作用下与乙酰乙酸乙酯环合并水解酯基，最终得到5-甲基-3-苯基-4-异噁唑甲酸，并以五氯化磷进行氯化，制得目标产物。

  Hydroformylation, a reaction that installs both a C–H bond and an aldehyde group across an unsaturated substrate, is one of the most important catalytic reactions in both industry and academia. Given the synthetic importance of creating new C–C bonds, the development of carboformylation reactions, wherein a new C–C bond is formed instead of a C–H bond, would bear enormous synthetic potential to rapidly

  加氢甲酰化是一种在不饱和底物上同时安装 C-H 键和醛基的反应，是工业界和学术界最重要的催化反应之一。鉴于创造新的 C-C 键的合成重要性，发展碳甲酰化反应，其中形成新的 C-C 键而不是 C-H 键，将具有巨大的合成潜力，可以在有价值的合成中迅速增加分子的复杂性醛类。然而，利用外源 CO 源的四组分反应固有的苛刻复杂性使得直接碳甲酰化反应的发展成为一项艰巨的挑战。在这里，我们描述了一种钯催化策略，该策略使用现成的芳酰氯作为碳亲电试剂和 CO 源，与空间拥挤的氢硅烷串联，进行炔烃的立体选择性碳甲酰化。将该协议扩展到四种化学发散性羰基化，进一步突出了该策略在羰基化化学中提供的创造性机会。

  initio molecular orbital calculations combined with qualitative estimates of steric interaction energies suggest that the lowest energy conformations of the acyloxyamidine linker are characterized by an extended planar CAr-C=N-O-C arrangement and either a syn-periplanar or anti-periplanar N-O-C-C(Ar') arrangement. Only the anti-periplanar conformation was observed in the crystal structures of three

  本文描述了新型的巨细胞病毒DNA聚合酶抑制剂的结构活性关系，该抑制剂具有两个通过酰氧基oxy连接子连接的芳基。对其中末端基团不同的一系列类似物的研究表明，在先导化合物的2,4-二氯苯基周围有非常窄的SAR，但苯并噻唑环的各种替代物均具有活性。其中最引人注目的是化合物78的异恶唑环，与先导化合物相比，其效价提高了30倍。我们还描述了10个类似物的设计，合成和评估，其中酰氧基am连接基被等位基团修饰或替代。结构-活性关系研究确定了接头-NH2基团是关键的药效学元素。从头算分子轨道计算与对空间相互作用能的定性估计相结合，表明酰氧基am连接子的最低能构象具有扩展的平面CAr-C = NOC排列以及同平面或反平面NOCC（Ar'）安排。在三个酰氧基am的晶体结构中仅观察到反平面构象。在这些研究的基础上设计的最有效的连接基修饰化合物是氨基甲酸20 20，在巨细胞病毒DNA聚合酶抑制试验中，氨基甲酸am的含量约为对照酰氧基am

  4-Hydroxyphenylpyruvate dioxygenase (HPPD, EC 1.13.11.27) is an important target site for discovering new bleaching herbicides. To explore novel HPPD inhibitors with excellent herbicidal activity, a series of novel N-aroyl diketone/triketone derivatives were rationally designed by splicing active groups and bioisosterism. Bioassays revealed that most of these derivatives displayed preferable herbicidal
