Two fluorescent benzo[g]quinoline derivatives were synthesized via Friedl?nder synthesis. Multilayered OLEDs using benzo[g]quinoline derivatives as the emitters showed unexpected emissions by electroplexes. Particularly, a device using 2-(naphthalen-3-yl)

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.

The diversity-oriented doubling strategy, which generates two 12-arylbenzoacridines from a single triarylmethanol precursor was developed to construct a library of drug candidates for the identification of biologically active compounds. Exploration of this 12-arylbenzoacridine library furnished a 4′-OH derivative as an estrogenic compound.
