Síntesis De Una Base De Schiff A Partir De Dopamina Y Cinamaldehído

Abstract

En el presente trabajo de investigación se reportan evidencias de la síntesis de una base de Schiff, a partir de dopamina y cinamaldehído, obtenida mediante condensación por vía húmeda. El compuesto se analizó por espectroscopia de infrarrojo y de ultravioleta visible y se compararon los resultados experimentales con los obtenidos mediante el método computacional de Teoría de la Densidad Funcional (DFT). Los análisis permitieron confirmar la obtención de la especie química: 4-(2-{[(1E,2E)-3-fenilprop-2-en-1-iliden]amino}etil)benzeno-1,2-diol.

Natural Compounds and Derivates: Alternative Treatments to Reduce Post-Harvest Losses in Fruits

“…Considering that the polymeric matrix may serve as a carrier for a wide range of additives, the use of edible coatings for disease management has grown in favor in recent years, and the application of combined treatments has significantly reduced the presence of phytopathogenic microorganisms in many studies [55,[101][102][103]. These activities are integral to fruit quality deterioration during the post-harvest stage, involving elevated ethylene levels.…”

“…One of the reactions that has been extensively studied is the Schiff base interaction, which involves the union of two organic compounds derived from a primary amine and an aldehyde or ketone. These interactions result in a double bond at C=N and also act as Lewis bases, expanding their applications in various environments [103]. This reaction facilitates the insertion of the functional groups of the chitosan used as a polymer matrix, enhancing its properties as an antimicrobial treatment when combined with other treatments possessing specific structural characteristics, such as citral and hexanal [104].…”
