Derivatives Of

A systematic investigation of the synthesis of 4-hydroxy-DL-proline and 2-amino-4-dihydroxyvaleric acid has been made, starting from the following derivatives of 2-amino-4-pentenoic acid: ethyl allylacetamidomalonate, ethyl allylacetamidocyanoacetate, 2-phthalimidopentenoic acid, allylacetamido-malonic acid, acetylallylglycine, 5-allylhydantoin, and 3-phenyl-5-allylhydantoin. Chlorine or bromine was added to the double bond of these compounds, and the reaction products were either derivatives of 5-halogenated-4-valerolactones or derivatives of 4,5-dihalogenated pentanoic acids, depending on whether the carboxyl group of the pentanoic acid was free or not when the halogenation reaction was carried out. Acid hydrolysis followed by treatment with barium hydroxide always gave mixtures, in different ratio, of 4-hydroxy-DL-proline and 2-amino-4,5-dihydroxyvaleric acid which were analyzed and isolated as the copper salts. In the case of 5-(2,3-dibromopropyl)hydantoin and 3-phenyl-5-(2,3-dibromopropyl)hydantoin, no cyclization could be obtained.

Influence Of Noise

Some new experimental evidence of complex irregular oscillations in the Belousov-Zhabotinsky reaction realized in a batch reactor is presented. The results were obtained under relatively low cerium and malonic acid concentrations. One-dimensional maps were used for general discussion, and particularly, for the influence of noise on the evolution of the oscillations.

At room temperature the chemical reaction between malonic acid (0.2 M) and KBrO3 (0.06 м) in 1 м H2SO4 is catalysed by cerium ions. The oscillation of the yellow Ce4+ ions can be observed directly during the reaction. By silica-gel chromatography the brominated products of the reaction have been identified as dibromoacetic acid and bromomalonic acid.

Kinetics Of

The kinetics of the Ce4+-decay and the formation of CO2 are measured in sulfuric acid solutions of malonic acid. The reaction rate is slowed down by Ce3+ -ions due to a reaction of Ce3+ with malonic acid radicals. The primary source of CO2 is the decarboxylation of malonic acid radicals. Implications on the mechanism of the BZ reaction are discussed.
