Synthesis of 3-aryl-4-(N-aryl)aminocoumarins via photoredox arylation and the evaluation of their biological activity

A new series of 3-aryl-4-(N-aryl)aminocoumarins was synthesized in two steps starting from the natural product 4-hydroxycoumarin using the photoredox catalysis for the key step. These conditions reactions allowed to make C[sbnd]C bonds is up to 95% yields

Synthesis of Indoles and Isoquinolones from Phenylmalonate Heterocycles

A new synthesis of the indole system has been achieved by cyclodehydrogenation of amino phenylmalonate heterocycles.Thus, the 4-amino coumarins 1a,b or the 4-amino-2-quinolones 1c-g are converted to the indoles 2 with palladium on charcoal in boiling diph
