Preparative synthesis of 2-[3-alkoxy-4-(hydroxy, alkoxy, acyloxy)phenyl]-1H-benzimidazoles proceeding from substituted benzaldehydes was written by Dikusar, E. A.;Potkin, V. I.. And the article was included in Russian Journal of Organic Chemistry in 2010.Related Products of 20665-85-4 This article mentions the following:
New functionally-substituted 2-[3-alkoxy-4-(hydroxy, alkoxy, acyloxy)phenyl]-1H-benzimidazoles of formula I, were synthesized in preparative yields from aldehydes of vanillin series, their ethers and esters by the reaction with 1,2-phenylenediamine in the presence of sodium hydrogen sulfite in DMF solution at 80鎺矯. In the experiment, the researchers used many compounds, for example, 4-Formyl-2-methoxyphenyl isobutyrate (cas: 20665-85-4Related Products of 20665-85-4).
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. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is 绾?valerolactone.Related Products of 20665-85-4
