Certain new nitrogen-substituted derivatives of cyclic imides phthalimide (a), 1,8-naphthalimide (b), and diphenimide (c), were synthesized aiming to obtain potent hypolipidemic agents. Thus, 2-(N-imido) propanoic acids, 2-(N-phthalimido)-2-methylpropionic acid, and their ethyl esters were synthesized (Target derivative A). Also their corresponding N-substituted-2-(N- imido) propionamides and 2-(N-phthalimido)-2-methylpropionamides were prepared (Target derivative B). In addition, N-phthalimidomethyleneoxy acetate was prepared. Some of the newly prepared compounds were subjected to 3D studies and were found to be superimposed on Clofibrate, which is the first generation of fibrate drugs. The preliminary evaluation of hypolipidemic activity of the newly prepared compounds against triton WR-1339-induced hyperlipidemia in rat showed that several derivatives have demonstrated significant lowering of serum total cholesterol and triglyceride levels at dose of 150 mg/kg/i.p. comparing with Fenofibrate which is one of the second generations of fibrate drugs.

(Chemical Equation Presented) An overall stereoconservative protection and deprotection method of amino and carboxyl groups is presented. N-Phthaloyl N-alkyl secondary amides of α-amino acids can be generated from corresponding N-phthaloyl amino acids by coupling reaction of N-alkylamines using mixed anhydride method. These secondary amides can be transformed by thermal rearrangement of intermediate nitrosoamides to O-alkyl esters with retention of configuration and excellent yields.

Azides (2a-d), in the base catalyzed decomposition with aromatic amines yielded the corresponding N-aryl-N'-alkyl ureas (4a-t) via Curtius rearrangement.However, the base catalyzed decomposition of 2 with phenylhydrazine took place via azido group displacement to afford phthalimido aliphatic acid phenylhydrazides (8a-d).Decomposition of azides (2a-d) in neutral medium yielded the corresponding sym-N,N'-di-alkyl ureas (9a-d), via Curtius rearrangement.
