An unprecedented deoxygenative arylation of aromatic carboxylic acids has been achieved, allowing the construction of an enhanced library of unsymmetrical diaryl ketones. The synergistic photoredox catalysis and phosphoranyl radical chemistry 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 is independent of substrate redox-potential, electronic, and substituent effects. It affords 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.

Recently, ll-diaminopimelate aminotransferase (ll-DAP-AT), a pyridoxal-5′-phosphate (PLP)-dependent enzyme, was reported to catalyze a key step in the biosynthesis of l-lysine in plants and Chlamydia. Previous screening of a 29201-compound library against
