their fast mode of action, smallmolecules are valuable tools to dissect the dynamic functions of kinesins during mitosis. In this study, we report the identification of optimized smallmoleculeinhibitors of the mitotic kinesin Kif18A. Using BTB-1, the first identified Kif18Ainhibitor, as a lead compound, we synthesized a collection of derivatives. We demonstrate that some of the synthesized derivatives

Irradiation of 2-nitrophenyl phenyl sulfoxide (I) gave 2-nitrosophenyl phenyl sulfone (II) as the sole product. The rearrangement was not affected by a quencher, but took a different course in the presence of a sensitizer or a halogen-containing solvent. When I with an electron-donating substituent at a 4′-position or electron-withdrawing one at a 4-position was irradiated, the corresponding II was
2-硝基苯基苯基亚砜(I)的辐照得到2-亚硝基苯基苯基砜(II)作为唯一产物。重排不受猝灭剂的影响,但在敏化剂或含卤素溶剂的存在下采取不同的过程。当在 4'-位带有给电子取代基的 I 或在 4-位带有吸电子取代基的 I 被照射时,相应的 II 以较低的产率获得。2-硝基苯基苯硫醚是光化学稳定的。结果表明,在 I 的激发单线态下,硝基的氧阴离子攻击正硫原子,发生氧转移。

When treated with nitrogen dioxide and ozone in inert solvent at 0 °C or below, arylsulfides underwent smooth oxidative nitration to give nitroaryl sulfones in good yield. Using this methodology. a series of mono- and di-nitrated arylsulfones were prepared from methyl phenyl sulfide and diphenyl sulfide and their physical data are presented.
当在惰性溶剂中在 0 °C 或更低温度下用二氧化氮和臭氧处理时,芳基硫化物经历了平稳的氧化硝化反应,以良好的收率得到硝基芳基砜。使用这种方法。由甲基苯硫醚和二苯硫醚制备了一系列单硝基和二硝基芳基砜,并提供了它们的物理数据。
Aluminum(III) Chloride Promoted Oxygen Transfer: Selective
Oxidation of Sulfides to Sulfoxides
An efficientselectiveoxidation of sulfides to sulfoxides has been developed by means of AlCl 3 -promoted oxygen transfer from phenyliodine diacetate [PhI(OAc) 2 ]. AlCl 3 proved to be the optimal Lewis acid for the activation of PhI(OAc) 2 . Various substituted sulfides were selectively transformed into the corresponding sulfoxides in good to excellent yields (≤99%). The high efficiency, excellent
