  Synthesis of Antibiotics WS 5995 A and C and Related Compounds by Palladium-Catalyzed Coupling of 2-Bromonaphthoquinones with Organostannanes

  摘要：

  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.

  development of the Gilvocarcins, a class of bioactive C-aryl glycoside natural products. More specifically, the origins behind the proposed O- to C-glycoside migration in the evolution of the biosynthesis for these classes of Angucycline antibiotic natural products. For stability reasons a 5a-carbasugar motif was used to mimic the sugar portion of the molecule and of synthetic ease the proposed abiotic rearrangement

  提出了两种非天然区域异构糖基化 Gilvocarcin 类似物作为模型化合物，以研究 Gilvocarcins（一类具有生物活性的C-芳基糖苷天然产物）生物合成发展背后的起源。更具体地说，在这些类Angucycline 抗生素天然产物的生物合成进化过程中，所提议的O - 到C - 糖苷迁移背后的起源。出于稳定性原因，使用 5a-carbasugar 基序来模拟分子的糖部分，并且为了合成容易，提议的非生物重排移动糖类似物及其O-糖苷键。两种提议的区域异构类似物是通过区域发散合成途径合成的，并具有类似光信的反向环化反应以安装碳糖基序。两种区域异构的 Gilvocarcin 类似物被评估为抗生素，Gilvocarcin M 作为对照。与 Gilvocarcin M 相比，两种异构体中只有一种显示出弱的抗生素活性。
