• Revisiting the Ullmann−Ether Reaction:  A Concise and Amenable Synthesis of Novel Dibenzoxepino[4,5-<i>d</i>]pyrazoles by Intramolecular Etheration of 4,5-(<i>o,o</i>‘-Halohydroxy)arylpyrazoles

  approach based on the palladium-catalyzed biaryl-ether linkage formation (Buchwald-Hartwig reaction) was also successfully applied, offering limitations with regard to the steric demand of the substituents. The synthesis of the key o,o'-halohydroxy-4,5-diarylpyrazole intermediates proceeds through the construction of the heterocyclic ring by a tandem amine-exchange/heterocyclization sequence of 3-N,N-(dimethylamino)-1

  通过在CuBr.DMS介导的o，o'-卤代羟基-4,5-二芳基吡唑上进行分子内Ullmann-醚反应，完成了一系列新的二苯并氧杂庚并[4,5-d]吡唑的简洁合成。基于钯催化的联芳基醚键形成（Buchwald-Hartwig反应）的另一种有用的方法也已成功应用，这对取代基的空间需求提供了限制。关键的o，o'-卤代羟基-4,5-二芳基吡唑中间体的合成是通过3-N，N-（二甲基氨基）-1,2-的串联胺交换/杂环化序列构建杂环而进行的二芳基丙烯酮与苯肼，然后进行碱性水解以进行脱保护。烯氨基酮前体可从便宜的水杨醛或苯乙酸衍生物开始，由相应的O-磺酰氧基和O-苯甲酰氧基邻位取代的1，2-二芳基酮方便地制备。已经完成了针对外周和中枢神经系统受体的初步结合亲和力实验，结果为阴性。

  This paper presents an efficient methodology for the preparation of dibenzoxepino[4,5-d]pyrazoles using a novel intramolecular palladium catalyzed diaryl ether formation. The effect of different chelating ligand systems, along with the unusual coupling reaction of phenoxides with aryl iodides and non-activated aryl moieties are also reported.

  10,11-Dihydro-11-[bis(methylthio)methylene]dibenzoxepin-10-one has been shown to be a useful three carbon synthon for the efficient regiospecific annulation of a variety of five- (pyrazoles, isoxazoles, thiophene, and γ-lactone) and six-membered (pyrimidines, pyridone and pyridines) heterocycles by cyclocondensation with heterobinucleophiles such as hydrazine, hydroxylamine, dimethylsulfonium methylide
