Semi-one-pot synthesis of phenanthrenesfrom styrenes and arenes was developed through cross-dehydrogenative coupling. A sequence of Heck-type coupling and photo-cyclization were involved and a variety of functionalities were tolerated. This method provides an effective and practical protocol towards the synthesis of substituted phenanthrenes.

The present invention provides a novel iridium complex and an organic light-emitting device including the novel iridium complex. The novel iridium complex includes three ligands, and two of them have a phenyl-naphtho[2,1-f]isoquinoline skeleton. The present invention also provides a display apparatus including the organic light-emitting device and an electrophotographic image-forming apparatus including a light source including the organic light-emitting device and including a photosensitive member.
Phenanthrene imidazole 3 (MF63) has been identified as a novel potent, selective, and orally active mPGES-1 inhibitor. This new series was developed by lead optimization of a hit from an internal HTS campaign. Compound 3 is significantly more potent than the previously reported indole carboxylic acid 1 with an A549 whole cell IC(50) of 0.42 microM (50% FBS) and a human whole blood IC(50) of 1.3 microM
