Ruzi, Rehanguli published the artcileDeoxygenative Arylation of Carboxylic Acids by Aryl Migration, Recommanded Product: Coumarin-6-sulfonyl chloride, the publication is Chemistry – A European Journal (2019), 25(55), 12724-12729, database is CAplus and MEDLINE.
An unprecedented deoxygenative arylation of aromatic carboxylic acids was achieved, allowing the construction of an enhanced library of unsym. diaryl ketones. The synergistic photoredox catalysis and phosphoranyl radical chem. allows for precise cleavage of a stronger C-O bond and formation of a weaker C-C bond by 1,5-aryl migration under mild reaction conditions. This new protocol was independent of substrate redox-potential, electronic, and substituent effects. It afforded a general and promising access to 60 examples of synthetically versatile o-amino and o-hydroxy diaryl ketones under redox-neutral conditions. Furthermore, it also brings one concise route to the total synthesis of quinolone alkaloid, (±)-yaequinolone A2, and a viridicatin derivative in satisfying yields.
