摘要：
Reactions of a chalcone derivative (synthesized earlier from usnic acid) with various oxidants (hydrogen peroxide, tert-butyl hydroperoxide, and dichlorodicyanobenzoquinone) gave new flavonols, dihydroflavonols, and flavones. Treatment of the starting chalcone with a nucleophilic reagent (NH2NH2 center dot H2O) afforded a dihydropyrazole-containing derivative.
