  超强酸合成的叔苯磺酰胺和苯并硫丹作为选择性hCA IX抑制剂：旨在了解叔磺酰胺抑制的新模式†

  摘要：

  在超强酸HF–SbF 5中合成了一系列叔（氟化）苯磺酰胺。规避原位问题通过低温NMR实验证明亚胺离子的形成，采用串联的超强酸催化的交叉偶联反应来合成苯并硫磺酸类似物。测试了这些叔苯磺酰胺作为人碳酸酐酶的抑制剂（hCA，EC 4.2.1.1）。这些化合物没有抑制广泛的脱靶hCA II同工型，并且显示出对与肿瘤相关的碳酸酐酶同工型IX的强选择性。证明了抑制剂的电子和结构形状对选择性的显着影响，证实了这类磺酰胺类药物的非锌键结合抑制方式。这项工作可以鉴定出该系列中的高选择性hCA IX抑制剂。

  A General Method for Palladium-Catalyzed Reactions of Primary Sulfonamides with Aryl Nonaflates

  摘要：

  A general method for Pd-catalyzed sulfonamidation of aryl nonafluorobutanesulfonates (aryl nonaflates) is described. A biaryl phosphine ligand, t-BuXPhos, formed the most active catalyst, and K3PO4 in tert-amyl alcohol was found to be the optimal base solvent combination for the reaction. The reaction conditions were tolerant of various functional groups such as cyano, nitro, ester, aldehyde, ketone, chloride, carbamate, and phenol. Heterocyclic aryl nonaflates were found to be suitable coupling partners. High yields of the coupled products were obtained from the reactions between inherently disfavored substrates such as electron-rich nonaflates and electron-poor sulfonamides. Kinetic data suggest reductive elimination to be the rate-limiting step for the reaction. The only limitation of this methodology that we have identified is the inability of 2,6-disubstituted aryl nonaflates to efficiently participate in the reaction.

  A simple copper-catalyzed redox coupling of sodium sulfinates and nitroarenes is described. In this process, abundant and stable nitroarenes serve as both the nitrogen sources and oxidants, and sodium sulfinates act as both reactants and reductants. A variety of aromatic sulfonamides were obtained in moderate to good yields with broad substrate scope. No external additive is employed for this kind

  A metal‐free reaction of nitrosoarenes, aryldiazonium tetrafluoroborates, and sulfur dioxide under mild conditions is developed, giving rise to sulfonamides in moderate to good yields. This transformation proceeds efficiently at room temperature in the presence of cyclohexa‐1,4‐diene with a broad reaction scope. Good functional group compatibility is observed, including cyano, halo, and ester. A plausible

A dramatic effect of the electronic and structural shape of the inhibitors on selectivity was demonstrated, confirming the non-zinc-bonding mode of inhibition of this class of sulfonamides.
