  PdCl 2 / DMSO催化的巯基-二硫键交换：不对称二硫键的合成

  摘要：

  通过使用简单的PdCl 2 / DMSO催化系统与对称的二硫化物进行硫醇交换，可以有效地制备不对称的二硫化物。给定的方法具有出色的官能团耐受性，广泛的底物范围和操作简便性。该反应对于诸如肽和药物之类的生物活性支架的后期功能化特别有用。还已经制备了含二硫化物的有机染料。这种转化可以扩展到硫醇-二硒化物或硫醇-二碲化物交换，从而提供RS-SeR'或RS-TeR'。

  2,2'-Dithiobis(benzothiazole) produces unsymmetric disulfides containing the 2-benzothiazolyl fragment in both high yield and purity when reacted with 1 equiv of a variety of alkane and arene thiols under mild conditions. In turn, these unsymmetric disulfides react with a variety of thiols to produce either symmetric disulfides or new unsymmetric disulfides in excellent yields. At room temperature, 2 equiv of most thiols are oxidized essentially quantitatively to the corresponding symmetric disulfide by 2,2'-dithiobis(benzothiazole). Thiols employed at various stages include 1-propanethiol, 2-propanethiol, 2-methyl-2-propanethiol, phenylmethanethiol, 2-mercaptoethanol, 2-mercaptoethylamine (MEA) hydrochloride, 2-methoxybenzenethiol, 4-methoxybenzenethiol, 4-aminobenzenethiol, 4-acetamidobenzenethiol, 4-bromobenzenethiol , 4-methylbenzenethiol, N-acetyl-L-cysteine, and sodium 2-mercaptoethanesulfonate (MESNA). Various disulfides were inactive in vivo against cyanide poisoning.
