Abstract:N-Tert-butoxycarbonyl-L-glutamine(1) was condensed and deprotected to give 3-aminopiperidine-2,6-dione hydrochloride (3); 3-nitro-3-phthalic anhydride (5) was obtained through the cyclization reaction of 3-nitrophthalic anhydride (4); 3 and 5 were refluxed in acetic acid to give 1,3-dioxo-2- (2,6-dioxopiperidine-3-yl)-5-nitroisoindoline (6). The final iron powder was used as reduce agent to give the desired product. The structure of the dopamine was confirmed by 1H-NMR. The reaction conditions were mild; the post-treatment was simple; no special equipment was required; the synthetic process was simple and the product quality was stable. The total yield of more than 45%. |
Key words:N-tert-butoxycarbonyl-L-glutamine; 3-nitrophthalic anhydride; synthesis |
