Diethyl ethoxymethylenemalonate Chemical Properties,Uses,Production
Chemical Properties
CLEAR COLOURLESS TO LIGHT YELLOW LIQUID
Uses
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.
Safety Profile
Moderately toxic by ingestion. A skin irritant. A combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes.
Purification Methods
Likely impurity is diethyl diethoxymethylene malonate which is difficult to separate from diethyl ethoxymethylene malonate by distillation, and it is necessary to follow the course of the distillation by the change in refractive index instead of boiling point. After a low boiling fraction is collected, there is obtained an intermediate fraction (n 20 1.414—1.458), the size of which depends on the amount of the diethoxymethylene compound. This fraction is fractionated through a 5inch Vigreux column (p 11) at low pressure avoiding interruption in heating. Fraction b 108-110o/0.25mm is ca 10o lower than the submitters' fraction (b 97.2o/0.25mm, n D 1.4612—1.4623) [Org Synth Coll Vol III 395 1955, Fuson et al.
