Aminoanthraquinones were successfully synthesized via two reaction steps. 1,4-Dihydroxyanthraquinone (1) was first subjected to methylation, reduction and acylation to give an excellent yield of anthracene-1,4-dione (3), 1,4-dimethoxyanthracene- 9,10-dione (5) and 9,10-dioxo-9,10-dihydroanthracene-1, 4-diyl diacetate (7). Treatment of 1, 3, 5 and 7 with BuNH2 in the presence of PhI(OAc)2 as catalyst produced seven aminoanthraquinone derivatives 1a, b, 3a, and 5a-d. Amination of 3 and 5 afforded three new aminoanthraquinones, namely 2-(butylamino)anthracene-1,4-dione (3a), 2-(butylamino)anthracene-9,10-dione (5a) and 2,3-(dibutylamino)anthracene-9,10-dione (5b). All newly synthesised aminoanthraquinones were examined for their cytotoxic activity against MCF-7 (estrogen receptor positive human breast) and Hep-G2 (human hepatocellular liver carcinoma) cancer cells using MTT assay. Aminoanthraquinones 3a, 5a and 5b exhibited strong cytotoxicity towards both cancer cell lines (IC50 1.1-13.0 μg/mL).

The reaction of 1-amino-4-acylaminoantraquinones with piperidine in the presence of CoCl2 and atmospheric oxygen gave the 2-aminated products in 75-80percent and similar reaction of 1-hydroxyantraquinone or 1-aminoantraquinone-2-sulfonic acid with butylamine gave the corresponding 4-aminated products, respectively.The effects of the α-substituents and the role of metal salts were discussed.
