Synthesis and Conformational Assignment of N-(E)-Stilbenyloxymethylenecarbonyl-Substituted Hydrazones of Acetone and o-(m- and p-) Chloro- (nitro-) benzaldehydes by Means of and NMR Spectroscopy
Eighteen new N-(E)-stilbenyloxyalkylcarbonyl-substituted hydrazones of ortho- (meta- and para-) chloro- (nitro-) benzaldehydes 1–18 and two analogous hydrazones of acetone 19-20 were prepared. The stereochemical behavior of 1–18 in dimethyl-d6 sulfoxide solution has been studied by NMR and NMR tec...

| description | Eighteen new N-(E)-stilbenyloxyalkylcarbonyl-substituted hydrazones of ortho- (meta- and para-) chloro- (nitro-) benzaldehydes 1–18 and two analogous hydrazones of acetone 19-20 were prepared. The stereochemical behavior of 1–18 in dimethyl-d6 sulfoxide solution has been studied by NMR and NMR techniques, using spectral data of 19 and 20 as supporting material. The E-geometrical isomers and cis-/trans-amide conformers have been found for these hydrazones. Energy barriers of isomers are reported. |
