通过一种基于活性阴离子聚合的新的迭代方法,已成功实现了明确定义的星形支化聚合物的连续合成。该方法仅涉及整个重复反应序列的两组反应条件:(a)苄基溴官能化的聚合物与封端有1-(3-叔丁基二甲基二甲基甲硅烷氧基甲基苯基)-的聚(取代的苯乙烯基)锂的偶联反应1-苯基乙烯连接两个聚合物链并引入苄基溴前体的3-叔丁基二甲基甲硅烷氧基甲基苯基和(b)引入的前体通过苯甲酰胺处理转化为苄基溴官能度(官能度)的反应(CH 3)3SiCl-LiBr。通过重复这两个反应,连续合成了一系列不对称的星形支化聚合物。他们涉及3臂ABC,4臂ABCD和A 2 B 2以及6臂A 2 B 2 C 2星,它们的A,B,C和D段为聚苯乙烯,聚(α-甲基苯乙烯),聚(分别为4-甲基苯乙烯),聚(甲基丙烯酸甲酯)或聚(甲基丙烯酸叔丁酯)。它们的高度的组成,分子量,和建筑同质性以及窄的分子量分布(中号瓦特/中号Ñ <1.05)通过SEC,的分析结果确认11
具有三足硅烷醇配体的亚烷基钼属于迄今为止已知的最具活性和选择性的炔复分解催化剂。本文描述了新一代产品,其特点是前所未有的稳定性和实用性,同时又不牺牲前代产品的化学优点。具体来说, 16型吡啶加合物很容易以克级制备,可以在空气中常规称重和处理,并且在手套箱外可以保持完好数月。然而,当溶解在甲苯中时,稳定吡啶配体的自发解离释放出具有优异性能和官能团耐受性的活性物质。具体来说,许多极性和非极性基团、各种质子位点和许多基本官能团被证明是兼容的。通过晶体学和光谱手段(包括95 Mo NMR)对催化剂进行了表征;它们的活性和稳定性进行了详细的基准测试,并且通过天然产物合成的高级应用来说明其有利特性。由于良好的整体应用特性和易于处理,该新系列的配合物预计将取代早期的催化剂,并有助于鼓励更频繁地使用炔复分解反应。

Mycobacterium tuberculosis thymidylate kinase (MtTMPK) has emerged as an attractive target for rational drug design. We recently investigated new families of non-nucleoside MtTMPK inhibitors in an effort to diversify MtTMPK inhibitor chemical space. We here report a new series of MtTMPK inhibitors by combining the Topliss scheme with rational drug design approaches, fueled by two co-crystal structures
