  generation of endocyclic vinyl carbene complexes was involved in this oxidative cyclization, which is distinctively different from previous protocols. This method allows the facile synthesis of various valuable naphthoquinones and carbazolequinones from readily available diynes under exceptionally mild reaction conditions and features a broad substrate scope and wide functional group tolerance. Moreover

  在过去的几十年中，涉及卡宾/炔烃复分解的卡宾级联反应引起了人们的极大关注，因为这种化学方法具有巨大的潜力来构建复杂的环状分子。然而，在这些反应中形成的乙烯基金属类胡萝卜素仅限于环外碳烯，并且内环乙烯基卡宾配合物的产生仍未探索。在这里，我们报告了前所未有的金催化末端二炔的氧化环化反应。重要的是，这种氧化环化过程涉及内环乙烯基卡宾配合物的产生，这与以前的方案截然不同。该方法可以在非常温和的反应条件下轻松地从容易获得的二炔中轻松合成各种有价值的萘醌和咔唑醌，并且具有广泛的底物范围和宽泛的官能团耐受性。而且，理论计算为该环化反应的不同选择性提供了进一步的证据。

  A diversity-oriented synthesis of hydroxylated aryl-quinones via C–H oxygenation reactions and their evaluation against Trypanosoma cruzi, the etiological agent of Chagas disease, was accomplished. With the use of ruthenium(II)- or palladium(II)-based catalysts, complementary regioselectivities were observed in the hydroxylation reactions and we have identified 9 compounds more potent than benznidazole

  完成了通过C-H 氧化反应以多样性为导向的羟基化芳基醌合成及其对锥虫病（恰加斯病的病原体）的评估。通过使用基于钌 (II) 或钯 (II) 的催化剂，在羟基化反应中观察到互补的区域选择性，我们已经在这些新型芳基化和羟基化醌中鉴定了 9 种比苯并硝唑 (Bz) 更有效的化合物。例如，5-羟基-2-[4-(三氟甲基)苯基]-1,4-萘醌 ( 4h ) 的 IC 50/24 h 值为 22.8 µM，比最先进的药物 Bz 的活性高 4.5 倍。本文提供了第一个应用 C-H 活化用于芳基化醌的位置选择性羟基化以及将这些化合物鉴定为杀锥虫药物候选物的例子。

• Palladium-catalyzed arylation of 1,4-naphthoquinones with aryl iodides and its synthetic application to the benzo[b]phenanthridine skeleton

  We report a Pd-catalyzed arylation of 1,4-naphthoquinones with aryl iodides. This reaction shows excellent functional group tolerance and high regioselectivity when using nonsymmetric 1,4-naphthoquinone. Furthermore, the resulting 2-aryl-1,4-naphthoquinone could be successfully converted into benzo[b]phenanthridine-7,12-dione through treatment with aqueous ammonia, followed by oxidative cyclization

  我们报告钯与芳基碘化物催化的芳基化的芳基化。当使用非对称的1，4-萘醌时，该反应显示出优异的官能团耐受性和高的区域选择性。此外，通过用氨水处理，然后使用MnO 2进行氧化环化，可以将所得的2-芳基-1,4-萘醌成功地转化为苯并[ b ]菲啶-7,12-二酮。
• Synthesis of Antibiotics WS 5995 A and C and Related Compounds by Palladium-Catalyzed Coupling of 2-Bromonaphthoquinones with Organostannanes

  The synthesis of arylnaphthoquinones can be performed simply by using as the key reaction the Pd(0)- and Cu(I)-catalyzed coupling of arylstannanes with 2-bromonaphthoquinones as the electrophiles. The palladium-catalyzed coupling reaction is general and allows for the functionalization of the unprotected quinone nucleus with alkyl, alkenyl, and aryl substituents. The coupling process tolerates the presence of a chelated peri hydroxyl and steric crowding of a 2,6-disubstituted arylstannane, although the preparation of a 2,6,2',6'-tetrasubstituted biaryl by coupling of 2-bromo-3,5-bis(acetyloxy)-1,4-naphthoquinone as the electrophile with 2,6-disubstituted arylstannanes was unsuccessful. The syntheses of quinonoid antibiotics WS 5995 A and C was accomplished by using this method as the key step. Benz[b]phenanthridinone 1, hypothetical intermediate in the biosynthesis of benz[b]phenanthridine alkaloids, was also prepared from antibiotic WS 5995 C or by addition of ammonia to the 2-aryl-1,4-naphthoquinone 41 followed by heterocyclization.
