A number of 2,3‐pyrrolidinediones have been synthesised by the condensation of phenylpyruvic, 3,4‐dimethoxyphenylpyruvic and α‐keto‐butyric acid with different aldehydes and amines. In some cases, cinchoninic acids were the products of condensations. The properties and reactions of the pyrrolidinediones have been studied.
