详细

Tetracyclic naphthoquinone-carbohydrate conjugates with an angular-fused heterocycle were obtained for the first time by the intramolecular condensation of naphthazarin thioglucosides in a mixture of n-butanol and methanesulfonic acid under reflux. The competing reaction is hydrolysis of the thioglucosidic bond with formation of trialkylmercaptonaphthazarins.
