Paragraph 0490, (2019/10/29)
Compounds as inhibitors of Activating Transcription Factor 6 (ATF6) are provided. The compounds may find use as therapeutic agents for the treatment of diseases or disorders mediated by ATF6 and may find particular use in the treatment of viral infections, neurodegenerative diseases, vascular diseases, or cancer.
Radical C-H Arylation of Oxazoles with Aryl Iodides: Dppf as an Electron-Transfer Mediator for Cs2CO3

A radical C-H arylation reaction of oxazoles with (hetero)aryl iodides using Cs2CO3 as base/electron donor and 1,1′-bis(diphenylphosphino) ferrocene (dppf) as a catalytic SET mediator is reported. The overall reaction likely follows the general base-promoted homolytic aromatic substitution mechanism through a radical-chain pathway. DFT calculations suggest that dppf forms a complex with CsCO3-, enhancing its SET reducing ability to generate an aryl radical from ArI.

Both base-assisted non-concerted metallation-deprotonation (nCMD) and concerted metallation-deprotonation (CMD) have been identified as two potent operating mechanisms in palladium-catalysed direct C-H coupling of oxazole and thiazole-4-carboxylate esters
C-H bond arylations and benzylations on oxazol(in)es with a palladium catalyst of a secondary phosphine oxide
Ackermann, Lutz,Barfuesser, Sebastian,Kornhaass, Christoph,Kapdi, Anant R.

An air-stable, well-defined palladium complex derived from secondary phosphine oxide (SPO) (1-Ad)2P(O)H enabled efficient C-H bond functionalizations with ample scope, which set the stage for direct arylations and benzylations of (benz)oxazoles, as well as unprecedented palladium-catalyzed C-H bond arylations on nonaromatic oxazolines.
Carbonates: Eco-friendly solvents for palladium-catalysed direct arylation of heteroaromatics
Dong, Jia Jia,Roger, Julien,Verrier, Cecile,Martin, Thibaut,Le Goff, Ronan,Hoarau, Christophe,Doucet, Henri
experimental part, p. 2053 - 2063 (2011/02/25)
The palladium-catalysed direct 2-, 4- or 5-arylation of a wide range of heteroaromatics with aryl halides proceed in moderate to good yields using the eco-friendly solvents carbonates. The best yields were obtained using benzoxazole or thiazole derivatives. The arylation of furan, thiophene, pyrrole, imidazole or isoxazole derivatives was found to require a more elevated reaction temperature. The Royal Society of Chemistry 2010.
