  Fluorescent nucleosides with ‘on–off’ switching function, pH-responsive fluorescent uridine derivatives

  摘要：

  We synthesized various pH-responsive fluorescent deoxyuridine derivatives (1a-g). These fluorescent nucleosides exhibited distinctive fluorescence at 470-600 nm in aqueous solvents containing methanol only at acidic to neutral pH values. In particular, 1f exhibited strong fluorescence only at pH range of 3.1-7.2 with a pK(a) of 6.1. Such pH-sensitive fluorescent nucleosides can be used as 'on-off' fluorescence switch for monitoring pH change in biological systems, particularly for cancer cell detection. (C) 2012 Elsevier Ltd.

  Organozinc reagents are among the most commonly used organometallic reagents in modern synthetic chemistry, and multifunctionalized organozinc reagents can be synthesized from structurally simple, readily available ones by means of alkyne carbozincation. However, this method suffers from poor tolerance for terminal alkynes, and transformation of the newly introduced organic groups is difficult, which

  有机锌试剂是现代合成化学中最常用的有机金属试剂之一，多官能化的有机锌试剂可以通过炔烃碳酰化从结构简单、容易获得的有机锌试剂中合成。但该方法对末端炔烃的耐受性较差，且新引入的有机基团难以转化，限制了其应用。在此，我们报告了一种由新开发的带有 1,10-菲咯啉-亚胺配体的铁催化剂催化的末端炔烃的乙烯基锌化方法。该方法提供了从现成的乙烯基锌试剂和末端炔烃中有效获取具有多种结构和官能团的新型有机锌试剂的途径。该方法具有优异的官能团耐受性（可耐受的官能团包括氨基、酰胺、氰基、酯、羟基、磺酰基、缩醛、膦酰基、吡啶基），良好的底物范围（合适的末端炔烃包括具有各种官能团的芳基、烯基和烷基乙炔）组），以及高化学选择性、区域选择性和立体选择性。该方法可以显着提高包括维生素A在内的各种重要生物活性分子的合成效率。机理研究表明，本研究开发的新型铁-1,10-菲咯啉-亚胺催化剂具有极其拥挤的反应袋，促进了化合物的高
