Design, synthesis and SAR of phenylamino-substituted 5,11-dihydro-dibenzo[a,d]cyclohepten-10-ones and 11H-dibenzo[b,f]oxepin-10-ones as p38 MAP kinase inhibitors
摘要:
The p38 MAP kinase is a key enzyme in inflammatory diseases as it is involved in the biosynthesis of proinflammatory cytokines such as TNF-alpha and IL-1 beta. Small molecule p38 inhibitors suppress the production of these cytokines and therefore p38 is a promising drug target for novel anti-inflammatory therapeutics. In this study, we report the design, synthesis, and SAR of novel N-substituted 11H-dibenzo[b,f]oxepin-10-ones and 5,11-dihydro-dibenzo[a,d]cyclohepten-10-ones as p38 inhibitors.

Carboxyl radical-assisted 1,5-aryl migration through Smiles rearrangement

We report herein, a silver(I)-catalyzed Smiles rearrangement of 2-aryloxy- or 2-(arylthio)benzoic acids to provide aryl-2-hydroxybenzoate or aryl-2-mercaptobenzoate dimer, respectively, through 1,5-aryl migration from oxygen or sulfur to carboxylate oxygen. Mechanistically, the aryl ether moiety undergoes an intramolecular ipso attack by the carboxyl radical followed by a C–O or C–S bond cleavage.

We report on the use of visible light photoredox catalysis for the radical Smilesrearrangement of 2-aryloxybenzoic acids to obtain aryl salicylates. The method is free of noble metals and operationally simple and the reaction can be run under mild batch or flow conditions. Being a redox neutral process, no stoichiometric oxidants or reductants are needed.
We report herein a cerium photocatalyzed aryl migration from an aryl ether to a carboxylic acid group through radical-Smiles rearrangement. This operationally simple protocol utilizes inexpensive CeCl3 as a photocatalyst and converted a variety of 2-aryloxybenzoic acids into aryl-2-hydroxybenzoates in good yields.
