Abstract

The four isomers of kainic acid, i. e. α- (α-I), β- (β-I), α-allo- (α-allo-I), and β-allo- (β-allo-I) kainic acids, are decomposed by ozonic oxidation and form corresponding methyl ketone compounds, α-methyl (α-III), β-methyl (β-III), α-allomethyl (α-allo-III), and β-allomethyl (β-allo-III) ketone compounds. The relationship between these and the methyl ketone compounds obtained to date was clarified.
