标题:双(二异丙氨基)氯膦和磺酰氯硫醇偶联合成混合三硫代磷酸酯
摘要:在这项研究中,我们报告了一种在环境温度温和条件下新型高效的混合三硫代磷酸酯的一锅法合成方法,无需补充添加剂.该方法的多功能性源于其利用多种硫醇作为亲核反应物,1-氯-N,N,N ',N'-四异丙基膦二胺[双(二异丙氨基)氯膦]作为磷前体,以及各种磺基氯化物作为亲电子硫源.值得注意的是,我们的研究范围超出了混合三硫代磷酸酯,涵盖了硒代二硫代磷酸酯的合成,强调了该合成方案的广泛适用性.

标题:Phosphotriester oligonucleotides, amidites and method of preparation
发明人：IMBACH JEAN-LOUIS; GOSSELIN GILLES; RAYNER BERNARD
摘要:Oligonucleotides having bioreversible phosphate blocking groups can be used as pro drugs for the oligonucleotides. The bio-reversible blocking groups can be removed by intercellular enzymes, particularly carboxyesterases, to provide the unprotected oligonucleotide. The oligonucleotides can be prepared via post synthesis alkylation reactions or utilizing amidite type chemistry wherein the bioreversible phosphorus protecting group is formed as an integral part of the amidite reagent.

摘要:Novel metal binding ligands are disclosed that may be coupled to peptides for use in methods of diagnosis and therapy. Peptides containing the ligands are produced using a method wherein ligand introduction or cyclization can be conducted at any point during the synthesis of the peptide. Such peptide derivatives are readily labeled with radiometals, such as isotopes of rhenium or technetium, while retaining their ability to tightly bind specific peptide receptors.
