Synthesis and Characterization of Novel Aromatic Substitutedγ- and δ-Ketoxime Esters

Abstract

By starting their corresponding keto esters 1a-j, aryl-, substituted aryl- and heteroaryl-containing γ- and δ-oximes 2a-2j (ten in total) were obtained. Proton nuclear magnetic resonance spectroscopy, carbon nuclear magnetic resonance spectroscopy, fourier transform infrared spectroscopy, mass spectrometry and elemental analyses were applied to the synthesized compounds for elucidating their structures and to find the (E)isomers
