摘要: Eleven novel (3-(substituted phenyl)-cis-4,5-dihydroisoxazole-4,5-diyl)bis(methylene) diacetate derivatives were synthesized in the present study. These dihydroisoxazole characterized by IR, (1)H NMR, (13)C NMR and elemental analyses. Their spectra measured Deuterochloroform (CDCl3). The correlation analysis for substituent-induced chemical shift (SCS) with Hammett substituent constant (σ), inductive (σI), different of resonance constants (σR, σR(o)) Swain-Lupton parameters (F, R) performed using SSP (single parameter), DSP (dual parameter) methods, as well single multiple regression analysis. From result analysis, effect on shifts was explained.
