SYNTHESIS AND PROPERTIES OF AZOLES AND THEIR DERIVATIVES. 27. REACTION OF POTASSIUM SALTS OF 3,5-DIARYL-2-ISOXAZOLYL-4-NITRONIC ACIDS WITH MINERAL ACIDS
Baran'ski, A.
, p. 328 - 330 (1991)
It has been shown that under the conditions of the Nef reaction potassium salts of 3,5-diaryl-2-isoxazolyl-4-nitronic acids form trans-3,5-diaryl-4-nitro-2-isoxazolines instead of the expected 3,5-diaryl-4-isoxazolones.The epimerization of the stereoisomeric 3,5-diaryl-4-nitro-2-isoxazolines in the presence of basic catalysts has been discussed.
SYNTHESIS AND PROPERTIES OF AZOLS AND THEIR DERIVATIVES. PART XII. REGIO- AND STEREOCHEMISTRY IN CYCLOADDITION REACTIONS OF β-NITROSTYRENES WITH BENZONITRILE n-OXIDE
Baranski, Andrzej
, p. 107 - 119 (2007/10/02)
1,3-Dipolar cycloaddition of trans-β-nitrostyrenes 1a-d to benzonitrile N-oxide 2 has been investigated.It was found that regioisomeric 4,5-dihydro-1,2-oxazoles were formed as primary products due to two possible orientations of reactants in the transitio
