Synthesis of aromatic azomethines from anesthesin and derivatives of vanillin and vanillal was written by Dikusar, E. A.;Potkin, V. I.;Kozlov, N. G.;Yuvchenko, A. P.. And the article was included in Vestsi Natsyyanal’nai Akademii Navuk Belarusi, Seryya Khimichnykh Navuk in 2007.Formula: C12H14O4 This article mentions the following:
Novel aromatic azomethines 3-R1O-4-R2OC6H3CH:NR3 (R1 = Me, Et; R2 = H, COMe, PhCH2CO, BrCH2CO, PhCO, etc.; R3 = 4-EtO2CC6H4), containing ether and ester groups from vanillin, vanillal and their esters, were synthesized in 90-94% yields by condensation of the corresponding aldehydes 3-R1O-4-R2OC6H3CHO with Et 4-aminobenzoate at reflux in absolute methanol in the absence of any catalyst. In the experiment, the researchers used many compounds, for example, 4-Formyl-2-methoxyphenyl isobutyrate (cas: 20665-85-4Formula: C12H14O4).
4-Formyl-2-methoxyphenyl isobutyrate (cas: 20665-85-4) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Formula: C12H14O4
