The action of boiling acetic anhydride on β-ureidesters, β-N-carbonyl esters and β-amino-esters was studied. It was shown that no cyclization of β-ureidoesters occurred and that N,N-diacetyl and N-acetyl-β-aminoesters were the reaction products in all three cases. A satisfactory separation of these compounds by chromatography was achieved and their physical properties determined. The mechanism of the

cyclic and acyclic imides were examined for hypolipidemicactivity in mice after dosing for 16 days at a dose of 20 mg/kg per day. The hypolipidemicactivity of the unsubstituted, N-butyl, N-3-oxobutyl, and N-2-carboxyethyl derivatives of diacetimide and succinimide were compared as well as the unsubstituted and N-substituted dibenzimide and diphenimide. It was shown that an imide functionality incorporated
