Transition-Metal-Free Synthesis of Phenanthridinones from Biaryl-2-oxamic Acid under Radical Conditions
摘要:
Na2S2O8-promoted decarboxylative cyclization of biaryl-2-oxamic acid for phenanthridinones has been developed. This work illustrates the first example of intramolecular decarboxylative amidation of unactivated arene under transition-metal-free conditions. Additionally, this approach provides an efficient and economical method to access biologically interesting phenanthridinones, an important structure motif in many natural products.

unprecedented selective synthesis of dihydrophenanthridine and phenanthridinederivatives through the cascade reactions of 2-arylanilines with alkynoates is presented. Mechanistic studies showed that the formation of the dihydrophenanthridine scaffold involves an initial C(sp2)–H alkenylation of 2-arylaniline with alkynoate followed by an intramolecular aza-Michael addition. When this reaction is carried out
The present invention relates to processes for preparing certain 2-pyridones and 2-pyridinols, to novel compounds of these two types and to their use as biologically active compounds, in particular for controlling harmful microorganisms in crop protection, in the medicinal field and in the protection of materials.
