dibenzo[b,f][1,4,5]oxathiazepine-5,5-dioxides and their heterocyclic analogs, which is an underexplored version of privileged tricyclic scaffolds for drug design. The reaction proceeds smoothly and regiospecifically under conventional heating conditions and delivers the target compounds in good to excellent yields. The approach represents a completely new disconnection of the dibenzo[b,f][1,4,5]oxathiazepine-5
仲邻羟基苯磺酰胺已作为一种双亲电子伙伴被研究出来,它是一种实用,简单,经济的二苯并[ b,f ] [1,4,5]氧杂氮杂卓-5,5-二氧化物及其杂环类似物的方法。用于药物设计的特权三环支架的未开发版本。该反应在常规加热条件下平稳且区域特异性地进行,并以良好至优异的产率递送目标化合物。该方法代表了二苯并[ b,f] [1,4,5] oxathiazepine-5,5-dioxide支架,可以根据取代方式使用新的化学空间。特别地,可以通过在环化反应中改变双亲电子芳族配偶的性质,方便地在三环框架内改变杂环。这已经通过合成三个迄今未描述的杂环三环支架得到了证明。如我们对一系列类似的成环过程所观察到的那样,环化反应是通过Smiles重排进行的。
