Descripción

Diethyl ethoxymethylenemalonate is used for synthesis of pyrido[3,2-e]pyrimido[1,2-c]pyrimidines. Initially, it was used to monitor lysine decarboxylase activity. It is useful in the determination of amino acids by precolumn derivatization by using reversed-phase high-performance liquid chromatography (HPLC). It plays an important role in the Gould-Jacobs reaction to prepare quinolines. For example, anile reacts with this reagent to give 4-hydroxyquinoline. It acts as an intermediate in the production of flumequine, which is a fluoroquinolone antibiotic.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Aplicaciones
El etoximetilenmalonato de dietilo se utiliza para la síntesis de pirido[3,2-e]pirimido[1,2-c]pirimidinas. Inicialmente, se utilizó para monitorear la actividad de la lisina decarboxilasa. Es útil para la determinación de aminoácidos por derivatización previa de las columnas mediante cromatografía líquida de alta eficacia (HPLC) de fase reversa. Desempeña un papel importante en la reacción de Gould-Jacobs para preparar quinolinas. Por ejemplo, el anilo reacciona con este reactivo para producir 4-hidroxiquinolina. Actúa como intermediario en la producción de flumequina, que es un antibiótico fluoroquinolona.

Solubilidad
Miscible con cloroformo, diclorometano y metanol. No miscible con agua.
