The Skraup reaction of amino-9H-thioxanthen-9-ones was conducted in the presence of glycerol, fuming sulfuric acid, nitrobenzone, iron(II) sulfate and boric acid. 1-Amino-9H-thioxanthen-9-one (1) gave 12H-[1]benzothiopyrano[2, 3-h]quinolin-12-one (5). 2-Amino-(2) and 3-amino-9H-thioxanthen-9-ones (3) gave angular-type products, 12H-[1]benzothiopyrano[3, 2-f]quinolin-12-one (6) and 7H-[1]benzothiopyrano[2, 3-f]quinolin-7-one (8), but did not give linear-type products. 4-Amino-9H-thioxanthen-9-one (4) gave 7H-[1]benzothiopyrano[3, 2-h]quinolin-7-one(10).
Functionalization of 9-thioxanthone at the 1-position: From arylamino derivatives to [1]benzo(thio)pyrano[4,3,2-de]benzothieno[2,3-b]quinolines of biological interest
hexacyclic derivatives of helicoidal nature. Evaluation of their photophysical properties revealed high fluorescence in polar media, indicating potential applications for biological imaging. These compounds being able to inhibit PIM1 kinase, their putative binding mode was examined through molecular modeling experiments. Altogether, these results tend to suggest the discovery of a new family of fluorescent

A new heterocyclic compound, [1]benzopyrano[2, 3, 4-kl]acridin-3-ol was synthesized by cyclization of xanthone derivatives. The key compound, 1-(3'-methoxyanilino)-xanthone, was prepared from 1-aminoxanthone. [1]benzopyrano[2, 3, 4-kl]acridin-3-ol analogues, [1]benzothiopyrano[2, 3, 4-kl]acridin-3-ol, pyrido[3', 2' : 5, 6]pyrano[2, 3, 4-kl]acridin-3-ol and pyrido[3', 2' : 5, 6]thiopyrano[2, 3, 4-kl]acridin-3-ol were synthesized by the same method.
