  在此，我们报告了通过吩噻嗪离子将易得的硼酸和有机锂进行无过渡金属氧化 C(sp 2 )–C(sp 2 ) 偶联的发展。使用该反应体系获得了各种联芳基、苯乙烯和二烯衍生物。该过程的关键是N-甲基吩噻嗪S-氧化物 (PTZSO)，它可以有效地将硼酸转化为吩噻嗪离子。使用理论计算和实验研究了使用 PTZSO 形成吩噻嗪的机制，从而深入了解 PTZSO 的独特反应性。

  摘要：

  梭菌的有趣的生物学特性，其中梭菌B是对宿主细胞具有低细胞毒性的有效抗病毒剂，使这些看似简单的结构挑战了合成靶标。进化出一种针对人球蛋白B的策略，其中三个连续的立体中心最终由Pd催化的不对称烯丙基烷基化（AAA）建立。后者涉及未稳定化的酮烯酸酯的不对称烯丙基化，产率为77％，ee为93％。通过使用该方法，（S）-5-烯丙基-2-异丙基-5-甲基-1-三氟甲磺酰氧基环戊烯可从2-甲基环戊酮分四个步骤获得。通过交叉偶联引入芳基单元在分子间进行，但在分子内失败。另一方面，还原除去三氟甲磺酸酯允许Heck反应实现芳基环的分子内引入。通过Heck反应中β-氢消除的区域选择性和还原的非对映选择性建立了带有异丙基的碳的立体化学，揭示了这种分子结构的非常规构象性质。成功的路线由2-甲基环戊酮和二甲基甲酚组成的15个步骤组成，阐明了基于Pd AAA的路线的效率。

  the synthesis of such compounds is complex. Here we describe a novel method for the generation of 1,2-dione containing diterpenoids using a unified approach, by which boronic acids are joined to vinyl bromo-cyclohexene derivatives via Suzuki coupling, followed by electrocyclization and oxidation to the o-phenanthroquinones. This has allowed the construction of a panel of miltirone analogues containing

  最近，基于丹参酮已经鉴定出一系列选择性的人羧酸酯酶抑制剂，其具有1，2-二酮基团的生物活性分子作为萘醌核心的一部分。不幸的是，这类化合物的合成很复杂。在这里，我们描述了一种使用统一方法生成含1,2-二酮的二萜类化合物的新方法，该方法将硼酸通过Suzuki偶联与乙烯基溴-环己烯衍生物连接，然后进行电环化并氧化成邻位-菲醌。这允许构建一组含有一系列取代基（甲基，异丙基，氟，甲氧基）的米替隆类似物，这些取代基已用于与两种人羧酸酯酶同工型发展初步的SAR。因此，我们已经合成这些酶（K的高度有效的抑制剂我 <15纳米），其保持所述芯丹参酮支架。因此，我们开发了一种简便易行且可重现的方法，用于合成abetanene类似物，从而产生了一系列米替农衍生物，这些衍生物将是评估羧酸酯酶生物学的有用工具化合物。
