Anthraquinone and its derivatives bearing hydroxy and amino moieties are of remarkable importance in pharmacological, biochemical and dye industries [1][2]. They have been described as important compounds for decades [3
-products derived from ring-closure reactions were only found when aliphatic amines with two carbon units between the amine and hydroxy functionality were used. In the synthesis of green and bluedyes, aromatic amines that cannot build six-membered rings were utilized. However, the ring-closure can be
