azachalcones and their oximes as tyrosinase inhibitors. Their inhibitory activities on mushroom tyrosinase using l‐3,4‐dihydroxyphenylalanine as a substrate were investigated. Two of the novel oxime derivatives synthesized were seen to be more potent than the positive control, kojicacid. Both the compounds 1b and 2b inhibited the diphenolase activity of tyrosinase in a dose‐dependent manner with their
2'-Hydroxy chalcone derivatives having heteroaromatic rings have been synthesized and their photochemical and photophysical properties have been examined in terms of tautomer produced by intramolecular hydrogen atom transfer reaction.

Convenient synthesis of flavanone derivatives via oxa-Michael addition using catalytic amount of aqueous cesium fluoride
flavanones, which included polycyclic aromatic and heterocyclic rings, were readily synthesized via oxa-Michael addition from the corresponding hydroxychalcones with a catalytic amount of aqueous cesium fluoride solution under mild conditions. This method could be applied to the scalable synthesis of eriodictyol as a known potent inhibitor of the SARS-CoV-2 spike protein.
