  A new, direct, and efficient synthesis of benzonaphthyridin-5-ones

  摘要：

  Microwave-assisted Suzuki cross-coupling reaction of 2-fluorophenylboronic acid with all orthochlorocyanopyridine isomers allowed the rapid syntheses of key intermediates for anionic ring closure, which was performed using potassium hydroxide under microwave irradiation to give benzonaphthyridin-5-ones in high yields.

  An unprecedented Rh(I)-catalyzed, amino-group-assisted C–H carboxylation of 2-arylanilines with CO2 under redox-neutral conditions has been developed. This reaction was promoted by a phosphine ligand with t-BuOK as the base and did not require the use of additional strong organometallic reagent. It enabled an efficient direct conversion of a broad range of 2-(hetero)arylanilines including electron-deficient

  在氧化还原中性条件下，开发了空前的Rh（I）催化的2-芳基苯胺与CO 2的氨基辅助CH羧基羧化反应。通过以t- BuOK为碱的膦配体促进了该反应，并且不需要使用其他强有机金属试剂。它能够将包括缺电子的杂芳烃在内的各种2-（杂）芳基苯胺有效地直接转化为各种菲啶酮。在初步的机理研究中还评估了反应的可能中间体。

  Phenanthridinone alkaloids crinasiadine 1 and N‐alkylcrinasiadines 6, 7, 8, 9, 10 have been synthesized based on palladium‐catalyzed tandem C–C and C–N bond formation starting from 2‐aminophenylboronic acid and 2‐bromobenzoate in short steps. Related alkaloids, 5,6‐dihydrobicolorine 2, trisphaeridine 3, and bicolorine 12 have also been synthesized.

  A series of aza-5[H]-phenanthridin-6-ones were synthesized and evaluated as inhibitors of poly ADP-ribose polymerase-1 (PARP-1). Inhibitory potency of the unsubstituted aza-5[H]-phenanthridin-6-ones (i.e., benzonaphyhyridones) was dependent on the position of the nitrogen atom within the core structure. The A ring nitrogen analogues (7-, 8-, and 10-aza-5[H]-phenanthridin-6-ones) were an order of magnitude less potent than C ring nitrogen analogues (1-, 2-, 3-, and 4-aza-5[H]-phenanthridin-6-ones). Preliminary stroke results from 1- and 2-aza-5[H]-phenanthridin-6-one prompted structure-activity relationships to be established for several 2- and 3-substituted 1-aza-5[H]-phenanthridin-6-ones. The 2-substituted 1-aza-5[H]-phenanthridin-6-ones were designed to improve the solubility and pharmacokinetic profiles for this series of PARP-1 inhibitors. Most importantly, three compounds from this series demonstrated statistically significant protective effects in rat models of stroke and heart ischemia.
