  描述了直接使用对甲苯磺酸与金属交换的蒙脱石代替对甲苯磺酰氯或对甲苯磺酸酐以高产率直接进行醇的甲苯磺酸化和二醇的选择性单甲苯磺酸酯化的经济经济路线。Fe 3+-蒙脱石粘土是金属交换蒙脱石中对于这种甲苯磺酸化反应最有效的催化剂。活性遵循以下顺序：Fe 3+ > Zn 2+ > Cu 2+ > Al 3+-蒙脱石> K10蒙脱石。可以高纯度实现二醇的区域选择性甲苯磺酸化成单甲苯基化的衍生物。在同时具有伯羟基和仲羟基的二醇中，甲苯磺酰化仅在伯羟基上发生。固体催化剂在环己醇甲苯磺酸化中举例说明的几个循环中显示出一致的活性。

  The present disclosure relates to bifunctional compounds, which find utility as modulators of tau protein. In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a VHL or cereblon ligand which binds to the E3 ubiquitin ligase and on the other end a moiety which binds tau protein, such that tau protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of tau. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of tau protein. Diseases or disorders that result from aggregation or accumulation of tau protein are treated or prevented with compounds and compositions of the present disclosure.

  本公开涉及双功能化合物，其作为tau蛋白的调节剂具有实用性。具体而言，本公开涉及含有一端结合到E3泛素连接酶的VHL或cereblon配体，另一端结合到tau蛋白的双功能化合物，使得tau蛋白与泛素连接酶靠近，以实现tau蛋白的降解（和抑制）。本公开展示了与tau蛋白降解/抑制相关的广泛药理活性。本公开的化合物和组合物用于治疗或预防由tau蛋白聚集或积累导致的疾病或紊乱。
• Reduction of Sulfonic Acids and Related Organosulfur Compounds with Triphenylphosphine–Iodine System
  作者：Shigeru Oae、Hideo Togo

  DOI：10.1246/bcsj.56.3802

  日期：1983.12

  excess iodine, however, these aliphatic sulfur compounds are converted eventually to the corresponding alkyl iodides. The relative reactivities of these sulfonyl derivatives in the reaction with the triphenylphosphine–iodine system are the following. Aromatic series: ArSO2Cl, ArSO2SAr′>ArSO2H>ArSO3R>ArSO3−HNBu3+ (or PyH+)>ArSO3H>ArSO2SO2Ar>>ArSO2CH2C(CH3)3, ArSO3Ar′. Aliphatic series: RSO2Cl, RSO2SR′,

  通过用三苯基膦和催化量的碘的混合物处理，芳烃磺酸、它们的钠盐和烷基芳烃磺酸盐可以很容易地还原成相应的芳烃硫醇，而烷烃磺酸、亚磺酸、二硫化物、硫代磺酸测试剂和磺酸盐也很容易类似地还原为相应的硫醇。然而，在用三苯基膦和过量碘的混合物处理后，这些脂肪族硫化合物最终转化为相应的烷基碘。这些磺酰基衍生物在与三苯基膦-碘体系反应中的相对反应性如下。芳族系列​​：ArSO2Cl、ArSO2SAr′>ArSO2H>ArSO3R>ArSO3−HNBu3+（或PyH+）>ArSO3H>ArSO2SO2Ar>>ArSO2CH2C(CH3)3、ArSO3Ar′。脂肪族系列：RSO2Cl、RSO2SR'、RSO2-HNBu3+>RSO3-HNBu3+>RSSR，RSO2H>RSO3H>RSH>RSO3R'。在这些反应中，带有供电子取代基的芳烃磺酸比具有供电子取代基的芳烃磺酸更容易被还原。

  公开（公告）日：2003-11-27

  A process for the production of compounds Ar—R 1 by means of a cross-coupling reaction of an organometallic reagent R 1 —M with an aromatic or heteroaromatic substrate Ar—X catalyzed by one or several iron salts or iron complexes as catalysts or pre-catalysts, present homogeneously or heterogeneously in the reaction mixture. This new invention exhibits substantial advantages over established cross coupling methodology using palladium- or nickel complexes as the catalysts. Most notable aspects are the fact that (i) expensive and/or toxic nobel metal catalysts are replaced by cheap, stable, commercially available and toxicologically benign iron salts or iron complexes as the catalysts or pre-catalysts, (ii) commercially attractive aryl chlorides as well as various aryl sulfonates can be used as starting materials, (iii) the reaction can be performed under “ligand-free” conditons, and (iv) the reaction times are usually very short.

  通过使用一种或多种铁盐或铁络合物作为催化剂或前催化剂，在有机金属试剂R1—M与芳香或杂芳底物Ar—X之间进行交叉偶联反应的方法，生产化合物Ar—R1。这一新发明相对于使用钯或镍络合物作为催化剂的传统交叉偶联方法具有显著优势。最值得注意的方面包括：(i) 昂贵和/或有毒的贵金属催化剂被廉价、稳定、商业可获得且毒理学上良性的铁盐或铁络合物替代作为催化剂或前催化剂，(ii) 商业上具吸引力的芳基氯化物以及各种芳基磺酸盐可用作起始材料，(iii) 反应可在“无配体”条件下进行，(iv) 反应时间通常非常短。
