2,3-DIHYDRO-BENZO-γ-PYRONE OXIMES. PART VII A SIMPLE METHOD OF DIFFERENTIATION OF ISOMERIC DERIVATIVES OF Δ2-ISOXAZOLINE AND FLAVANONE OXIMES. A CORRECTION OF SOME STRUCTURES

The simple method of differentiation of isomeric derivatives i.e. (E)-2,3-dihydro-2-(4-ethoxyphenyl)-4H-benzopyran-4-one oxime (2) and corresponding Δ2-isoxazoline (3) on the basis of their UV and 1H NMR data, allows us to establish that the 2,
