The light “on-off” stepwise one-pot method for 3,4-diaryl coumarins with potential AIE properties

An efficient one-pot method involving visible-light-induced cyclization and Pd-catalyzed Suzuki cross-coupling processes to construct 3,4-diaryl coumarins is developed. Under the light on-off optimized conditions, a series of alkynoates and aryl boronic a

Synthesis of 6-aryl-5-phenyl-7H-furobenzopyran-7-ones and 8-aryl-7-phenyl-9H-benzofurobenzopyran-9-ones under phase transfer catalysis conditions

The synthesis of 6-aryl-5-phenyl-7H-furobenzopyran-7-ones (5) and 8-aryl-7-phenyl-9H-benzofurobenzopyran-9-ones (9) under phase transfer catalysis condition is described.
