Treatment of 3-nitrophthalimide (I) with ethyl chloroformate and triethylamine produced 3-nitro-N-(ethoxycarbonyl)phthalimide (II), which was condensed with L-glutamine tert-butyl ester hydrochloride (III) to afford the phthaloyl glutamine derivative (IV). Acidic cleavage of the tert-butyl ester of (IV) provided the corresponding carboxylic acid (V). This was cyclized to the required glutarimide (VI) upon treatment with thionyl chloride and then with triethylamine. The nitro group of (VI) was finally reduced to amine by hydrogenation over Pd/C.

合成路线2

The cyclization of N-(benzyloxycarbonyl)-L-glutamine (I) by means of CDI in THF gives the piperidinedione (II), which is deprotected by means of HBr in AcOH to yield 3(S)-aminopiperidine-2,6-dione (III).The condensation of (III) with 3-nitrophthalic anhydride (IV) in hot DMF/AcOH affords 3(S)-phthalimido-piperidine-2,6-dione (V), which is finally reduced with H2 over Pd/C in dioxane/methanol to provide the target thalidomide derivative.
