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. 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.Synthetic Route of C12H14O4

Polyacetylenic compounds. CLVII. Components of Coreopsis nuecensis was written by Bohlmann, Ferdinand;Zdero, Christa. And the article was included in Chemische Berichte in 1968.Synthetic Route of C12H14O4 This article mentions the following:

5-(3-Acetoxy-1-propynyl)-2-phenylthiophene (I), 3,4-(MeO)(Me2CHCO2)C6H3CH(O2CCHMe2)CH:CH2 (II), 3,4-(MeO)(Me2CHCO2)C6H3CH(OAc)CH:CH2, cis-1′,2′-epoxyconiferyl alc. diisobutyrate (III) and cis-1′,2′-epoxy-3′-O-(2-methylbutyryl)-4-O-isobutyrylconiferyl alc. were isolated from C. nuecensis roots, in addition to the known C2H2 derivatives Syntheses were carried out for I, II, and III. In the experiment, the researchers used many compounds, for example, 4-Formyl-2-methoxyphenyl isobutyrate (cas: 20665-85-4Synthetic Route of C12H14O4).
