features providing new insights into the role of the substituents found in both the pyridyl core as well as the side chain. A strategic late stage heterobenzylic Stille cross-coupling reaction of the pyridyl core with the fully elaborated side chain permitted ready access to the analogues in which each half of the molecule could be systematically and divergently modified. The pyridyl cores were assembled
详细介绍了 piericidin A1 和 B1 的全合成及其对一系列关键类似物制备的扩展,包括 ent-piericidin A1 (ent-1)、4'-deshydroxypiericidin A1 (58)、5'-desmethylpiericidin A1 (73)、4'-deshydroxy-5'-desmethylpiericidin A1 (75) 和相应的类似物 51、59、76 和 77,带有简化的法呢基侧链。对这些关键类似物的评估以及从它们进一步功能化衍生的那些类似物,允许对关键结构特征进行扫描,从而提供对在吡啶基核和侧链中发现的取代基的作用的新见解。吡啶基核与完全精心设计的侧链的战略性后期杂苄基斯蒂勒交叉偶联反应允许容易地获得类似物,其中分子的每一半都可以被系统地和发散地修饰。吡啶基核通过 N-磺酰基-1-氮杂丁二烯的逆电子需求 Diels-Alder 反应组装而
