synthesized by electrophilicsubstitutionreactions of hydroxy- and bromoadamantanes with salicylic acid, as well as by reactions of 5-(3-hydroxyadamantan-1-yl)salicylic acid with carbon and nitrogen nucleophiles, in trifluoroacetic acid. The possibility of selective hydroxylation of the adamantane fragment in 5-(adamantan-1-yl)salicylic acid with sulfuric acid in trifluoroaceticanhydride has been demonstrated
