Reactions of vanillin and vanillal esters with 6-quinolylamine and phenidone was written by Gusak, K. N.;Kozlov, N. G.. And the article was included in Russian Journal of General Chemistry in 2005.Name: 4-Formyl-2-methoxyphenyl isobutyrate This article mentions the following:
2-Alkoxy-4-(11-oxo-9-phenyl-7,8,9,10,11,12-hexahydrobenzo[b][4,7]phenanthrolin-12-yl)phenyl esters, e.g., I, were prepared by condensation of vanillin or vanillal alkanoates with 6-quinolylamine and Phenidone. According to the 1H NMR spectra, the target products were formed as mixtures of diastereomers. In the experiment, the researchers used many compounds, for example, 4-Formyl-2-methoxyphenyl isobutyrate (cas: 20665-85-4Name: 4-Formyl-2-methoxyphenyl isobutyrate).
4-Formyl-2-methoxyphenyl isobutyrate (cas: 20665-85-4) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Name: 4-Formyl-2-methoxyphenyl isobutyrate
