SYNTHESIS AND PROPERTIES OF AZOLES AND THEIR DERIVATIVES. 10. SYNTHESIS OF 3,5-DIARYL-4-NITROISOXAZOLES

A method was proposed for the synthesis of 3,5-diaryl-4-nitroisoxazoles entailing the bromination of potassium salts of the corresponding 3,5-diaryl-Δ2-isoxazolinyl-4-nitronic acids.The method may be used for the conversions of both the trans and cis isomers of 3,5-disubstituted 4-nitro-Δ2-isoxazolines.

SYNTHESIS AND PROPERTIES OF AZOLES AND THEIR DERIVATIVES. PART XX. STUDIES ON THE THERMOLYSIS OF REGIO AND STEREOISOMERIC DIARYLNITRO-Δ2-ISOXAZOLINES

Thermolysis of stereoisomeric 3,5-diaryl-4-nitro-Δ2-isoxazolines 1, 3, depending on the applied solvent, leads to 3,5-diarylisoxazoles 4 or mixtures of 3,5-diarylisoxazoles 4 and 3,5-diaryl-4-nitroisoxazoles 6.Under similar conditions, 3,4-diar
