  摘要：

  描述了双官能螯合剂（BFCA）对全氟芳基叠氮化物的官能化，该双官能螯合剂能够与（99m）Tc（对于γ成像）和（188）Re（对于放射疗法）形成高比活络合物。还介绍了含有N（2）S（2），N（4）和N（3）S供体基团的多供体BFCA的合成，该供体基团对调节药代动力学参数可能很重要，其中包括咪唑，吡啶和吡嗪官能团。全氟芳基叠氮化物在BFCA上各个位置的功能化产生了新型的双功能光不稳定螯合剂（BFPCA），可用于共价连接生物分子。在模型溶剂二乙胺中的代表性Re-BFPCA 8a可以在不使8a的金属离子分解的情况下，获得高产率的分子间NH插入产物。通过分析技术对所有源自8a在二乙胺中的光解产物进行了表征，并提出了形成不同光解产物的合理机制。Re-BFPCA 8a分子间NH插入的高产率扩展到在水性条件下标记人血清白蛋白（HSA）和Fab片段。此处开发的光标记技术提供了一种新方法，可将诊断和治疗上有用

• Selective Preparation of β-Monoesters of Mercaptosuccinic Acid with Acid or Base Labile Sulfur Protecting Groups and Esters

  Abstract Sulfur protected mercaptosuccinic acid β-monoesters were prepared by two complimentary methods. Alkylation of enolates of hemithioacetal protected mercaptoacetic acid with t-butyl bromoacetate directly provides the base stable t-butyl esters 2a and 2b. Alternatively, protection of the α-carboxylate and thiol as an oxathiolone permits the preparation of the base labile S-acyl protected mercaptosuccinic

  摘要 通过两种互补的方法制备了硫保护的巯基琥珀酸β-单酯。半硫代缩醛保护的巯基乙酸的烯醇化物与溴乙酸叔丁酯的烷基化直接提供碱稳定的叔丁酯 2a 和 2b。或者，将α-羧酸盐和硫醇作为氧杂硫酮进行保护允许制备碱不稳定的S-酰基保护的巯基琥珀酸酯2c和2d。
• Latent mercaptans as multi-functional additives for halogen-containing polymer compositions

  Halogen-containing polymer compositions comprising a latent mercaptan-containing heat stabilizer composition substantially free from the offensive odor typically associated with mercaptans are protected during processing by the degradation products of the latent (i.e., blocked) mercaptan which include a free mercaptan. Other products of the degradation are believed to include carbocations of the blocking moiety which are stabilized by a molecular structure in which the electron deficiency is shared by several groups. The latent mercaptan may be the sole heat stabilizer additive but the free mercaptan released during processing may also synergize the activity of metal-based heat stabilizers such as metal salts and organometallic stabilizers such as organotin carboxylates and mercaptides in the polymer composition. The odor of primary mercaptan-containing heat stabilizers in halogenated polymer compositions is masked by a small amount of a latent mercaptan. The latent mercaptans also serve as intermediates in the preparation of anti-oxidants, anti-microbial agents, photostabilizers, and primary heat stabilizers. Highly effective heat stabilizers are prepared by the condensation of formaldehyde and a para-phenol and further condensation of the crude product with a mercapto-containing compound.

  Flexible, semi-rigid, and rigid vinyl chloride polymer compositions comprising a latent mercaptan-containing heat stabilizer are substantially free from the offensive odour typically associated with mercaptans and are protected during processing by the degradation products of the latent (i.e., blocked) mercaptan which include a free mercaptan. The free mercaptan thus released enhances the activity of metallic-based heat stabilizers such as zinc carboxylates and organotin carboxylates and mercaptides in the polymer composition. Other products of the degradation are believed to include carbocations of the blocking moiety which are stabilized by a molecular structure in which the electron deficiency is shared by several groups. The latent mercaptan is selected from a 2-S-(tetrahydropyranyl)-thioalkanol, a carboxylic acid ester thereof, a 2-S-(tetrahydropyranyl)-thioglycolic acid, and an ester thereof.
