Synthesis of 1-oxa-9-azaspiro[5.5]undecane-9-sulfonamides bearing a diverse molecular periphery and a rare zinc-binding group for carbonic anhydrase interrogation
Attachment of a 5-nitrofuroyl moiety to spirocyclic piperidines produces non-toxic nitrofurans that are efficacious in vitro against multidrug-resistant Mycobacterium tuberculosis
belonging to the nitrofuran class of antimicrobials has been developed via conjugation of the nitrofuran moiety to a series of spirocyclic piperidines through an amide linkage. It proved to have comparable activityagainst drug-sensitive (H37Rv) strain as well as multidrug-resistant, patient-derived strains of Mycobacteriumtuberculosis. The compound is druglike, showed no appreciable cytotoxicity toward

The chemoselectivity of halo(het)arene sulfonyl halide aminations is studied thoroughly under parallel synthesis conditions, and the scope and limitations of the method are established. It is shown that SNAr-reactive sulfonyl halides typically undergo sulfonamide synthesis during the first step; the second amination is also possible provided that the SNAr-active center is sufficiently reactive.

在平行合成条件下深入研究了卤代(杂)芳烃磺酰卤胺化物的化学选择性,并确定了该方法的范围和局限性。结果表明, SN Ar反应性磺酰卤通常在第一步中进行磺酰胺合成;如果SN Ar活性中心具有足够的反应性,则第二次胺化也是可能的。相反,带有芳基化部分的磺酰氟在适当的控制下在后一个反应中心发生选择性转化。进一步的硫-氟化物交换(SuFEx)也是可能的,这对于某些磺酰卤类特别有价值。开发的两步并行双胺化方案提供了对 66.7 亿个化合物的合成可处理 REAL 型化学空间的访问(预期合成成功率 76%)。
