摘要:在过去的几年中,我们已经证明 2 取代的氮丙啶 (1) 是制备各种胺的非常好起始材料,其合成策略包括官能团操作和氮丙啶的开环反应.为了丰富带有氮丙啶环的官能团,需要在不损害其他官能团(包括苯乙基或氮丙啶环本身)的情况下对烯烃进行化学选择性还原.最近,我们发现了一种用邻硝基苯磺酰肼 (Nbsh) 选择性还原 2-乙烯基氮丙啶中双键的方法,收率非常好.该协议适用于大多数与氮丙啶环相连的烯烃,如化合物 2 所示.但是,将该协议用于一般目的时存在一些缺点.Nbsh 试剂应在使用前由相应的邻硝基苯磺酰氯和肼制备.此外,该过程需要相当多的试剂和碱,通常为 4 当量的 Nbsh 和 8 当量的 Et3N.其中大部分应在完成反应后除去.为了避免这些缺点,需要一种在金属催化剂存在下使用氢气的更好方法.众所周知,氮丙啶环可能无法承受任何催化氢化条件.我们决定找到一种方法来实现还原氢化方法,通过仔细选择金属催化剂适

标 题 :Synthesis of stable quinone and photoreactive ketone phosphoramidite reagents for solid phase synthesis of photoreactive-oligomer conjugates
发明人：FENSHOLDT JEF
权利人:EXIQON AS
摘要:Quinone phosphoramidite reagents as well as photoreactive ketone phosphoramidite reagents, such as anthraquinone phosphoramidite reagents and benzophenone phosphoramidite reagents were synthesized and used for the solid phase synthesis of photoreactive-oligonucleotide conjugates. These phosphoramidite reagents are stable, suitable for large-scale synthesis and designed for automated solid phase synthesis of oligomers terminating in a photoreactive moiety.

摘要:This invention describes various processes for synthesis and resolution of racemic amino-substituted fused bicyclic ring systems. One process utilizes selective hydrogenation of an amino-substituted fused bicyclic aromatic ring system. An alternative process prepares the racemic amino-substituted fused bicyclic ring system via nitrosation. In addition, the present invention describes the enzymatic resolution of a racemic mixture to produce the (R)- and (S)-forms of amino-substituted fused bicyclic rings as well as a racemization process to recycle the unpreferred enantioner. Further provided by this invention is an asymmetric synthesis of the (R)- or (S)-enantiomer of primary amino-substituted fused bicyclic ring systems.
