标题:氟甲基-2,4,6-三硝基苯磺酸盐:一种新型亲电单氟甲基化试剂
摘要:氟甲基2,4,6-三硝基苯磺酸盐是首次制备,并被鉴定为易于使用的单氟甲基化试剂.它的固态分子结构已经通过单晶x射线衍射研究确定.事实证明,该试剂可有效地将ch 2 F基团亲电子引入到选定的硫属元素和氮亲核试剂中.已经使用氟甲基-2,4,6-三硝基苯基磺酸酯合成了各种双官能n,O-亲核试剂的单氟甲基衍生物.由于阴离子具有非常好的结晶性,因此可以通过x射线晶体学技术轻松地表征难以通过核磁共振波谱鉴定的氟甲基化产物以及副产物.

摘要:The present invention relates to gold binding peptides and shape- and size-tunable synthesis of gold nanostructures. The present inventions are very useful for the production of well-designed, gold-based architectures. The size- and shape-specific gold nanostructure materials prepared by the present invention may find use as: highly conductive interconnections for single-electron transistors, catalysts for the oxidation of carbon monoxide; biological and chemical sensors; and as contrasting agents for electron microscopic and medical imaging applications.

标 题:Method for the solid-phase synthesis of retro-inverso polypeptides
摘要:This invention relates to a method for the solid-phase synthesis of polypeptides containing retro-inverted peptide bonds, using polydimethylacrylamide-co-acryloylsarcosimethylester resin cross-linked with N, N min -ethylene-bis-acrylamide as the insoluble support for lengthening the polypeptide chain in stages by the addition of suitable amino acid derivatives and/or peptides in succession. In particular, the method described in the present invention allows the easy preparation, on the polymer matrix, of monoacylated gem-diamino residues using the reagent I, I-bis (trifluoroacetoxy) iodobenzene in mixed aqueous-organic solvents.

发明人：TOTH ISTVAN; DEKANY GYULA; KELLAM BARRY
权利人:ALCHEMIA PTY LTD
摘要:This invention relates to methods for synthesis of organic compounds, and in particular to compounds useful as protecting and linking groups for use in the synthesis of peptides, oligosaccharides, glycopeptides and glycolipids. The invention provides protecting and linking groups that are useful in both solid phase and solution synthesis, and are particularly applicable to combinatorial synthesis.
