Abstract

PURPOSE: To obtain the title compounds useful as intermediates for the production of amino acids, other medicines, α-oxy acid, etc., economically in high yield, by the oxidative decomposition of α, β-unsaturated carboxylic acids or their esters in the presence of a heavy metal catalyst and an oxidizing agent.
CONSTITUTION: The title compounds are obtained by the oxidative decomposition of α, β-unsaturated carboxylic acids or their esters in the presence of a catalyst and an oxidizing agnet. Metals of the % group in the periodical table or their compounds (e.g. ruthenium, osmium, ruthenium, dioxide) are used as the catalyst in an amount of 0.00001W1 mole per mole of the raw maerial. Chlorine in the presence of water, halogenoacids and their salts, peracetic acid, etc. are used as the oxidizing agent in an amount of 1W100 moles per mole of the raw material. The raw material is preferably a compound having hydrocarbon substituent (e.g. methyl, phenyl) at the α-position, and methacrylic acid esters are especially suitable.
