e (IIa-o), containing both electron-donor and electron-acceptor substituents in the phenoxyl part of the molecule. These compounds were obtained by the action of phosphorus chloride on the complex of the compound (Ia-o) with boron trifluoride etherate in dimethylformamide. The acylation of the compound (II) with acetic anhydride in the presence of pyridine gave the corresponding acetates (IIl).
A method of reducing the virulence of a bacterium that expresses accessory gene regulator A (AgrA) or an ortholog of AgrA includes administering to the bacterium an amount of a pharmaceutical composition effective to inhibit the synthesis of one or more virulence factors by the bacterium, the pharmaceutical composition including an AgrA antagonist.

3-substituted 2-methyl/2-benzyl/2-(2-phenethyl)chromones with trifluoroacetic anhydride in presence of potassium trifluoroacetate was investigated. It was established that the nature of substituent in position 3 of chromone ring has no crucial influence/limitation on this reaction, whereas only in the case of 2-benzyl substituent (in addition to 2-sec-alkyl group) no reaction was occurred at all. Reaction of
