Preparative methods for the synthesis of 2-(5-arylisoxazol-4-yl)benzoic acids and 2-(5-(2-hydroxyaryl)-isoxazol- 4-yl)benzoic acids have been developed. It is shown that amides of 2 ′ -deoxybenzoinecarboxylic acids are uni ver- sal starting compounds for the preparation of structurally diverse 4,5-diarylsubstituted isoxazoles.
