The unprecedented carbodiimide-mediated condensation between pyridines and anthranilicacids via pyridines dearomatization at room temperature has been developed to provide a straightforward approach to pyridoquinazolones. The value of this approach...
Derivatives of a CYP1A2 inhibitor rutaecarpine were synthesized to have potent and selective inhibition of human CYP1 members. Structural modelling shows a good fitting of rutaecarpine with the putative active site of human CYP1A2. Among the derivatives. 10- and 11-methoxyrutaecarpine are the most selective CYP1B1 inhibitors. 1-Methoxyrutaecarpine and 1,2-dimethoxyrutaecarpine are the most selective CYP1A2 inhibitors.

Visible-Light-Mediated Synthesis of Rutaecarpine Alkaloids through C–N Cross-Coupling Reaction
visible-light-initiated cross-dehydrogenative-coupling amination is described, featuring metal- and photocatalyst-free, at room temperature, and using air as an oxidant. The reaction provides a facile approach for the synthesis of rutaecarpine and its derivatives. The substrates with electron-withdrawing groups give higher yields than those with electron-donating groups, but the substituent position
