The synthesis of phenanthridinones via denitrogenative annulation of 1,2,3‐benzotriazin‐4‐(3H)‐ones with arynes catalysed by Ni(0)/dppm was successfully developed. A variety of phenanthridinones were prepared in good to excellent yields. Based on this method, nature product, N‐methylcrinasidine, was synthesized.

Catalytically asymmetricsynthesis of atropisomeric compounds is an important research area in organic synthesis. However, in comparison with C–C atropisomers, the atropisomers caused by the restricted rotation of C–N single bonds have been given less attention because of the limited methods for accessing these compounds. Herein we report a Cu-catalyzed enantioselective intramolecular Ullmann-type
The present invention relates to electronic devices, in particular organic electroluminescent devices, comprising compounds of the formula (1), to the corresponding compounds, and to a process for the preparation of these compounds.

A straightforward synthetic strategy to construct biologically relevant phenanthridinones and quinolinones was developed via visible-light-promoted direct oxidative C-H amidation. In this photocatalytic system, amidyl radicals can be generated by homolysis of the N-H bond of simple amide precursors via single-electron transfer under blue LED illumination, which leads to oxidative intramolecular C-H amidation. Moreover, an efficient synthetic strategy using a photocascade enabled facile assembly of quinolinone structures through a catalytic sequence involving triplet energy (E-T) transfer based E/Z olefin isomerization and subsequent photocatalytic generation of amidyl radical intermediates.
