An efficient one-pot procedure has been developed for the synthesis of cagealcohols with hydroxy groups in the bridgehead positions. The procedure includes initial nitroxylation with nitric acid or a mixture of nitric acid with acetic acid and subsequent hydrolysis in the presence of urea.

Hydroxyphenyl adamantanes are represented by the general formula (1):
1
wherein R is an alkyl group, cycloalkyl group or phenyl group; m is 0 or an integer 1 or 2; l is 0 or 1; when l is 1, hydroxy groups of substituted hydroxyphenyl groups at positions 1 and 3 are together in para-position; n is 0 or an integer 1, 2 or 3; and when l is 0, n is an integer 1, 2 or 3.

A series of diesters on the basis of 5,7-dimethyl-1,3-adamantanediol and 5,7-dimethyl-1,3- bis(hydroxymethyl)adamantane and C3–C10 aliphatic acids have been synthesized and their physicochemical and thermo-oxidative properties have been studied. The properties of the esters obtained have been compared to those of trimethylolpropane and neopentyl glycol esters.

A method for efficiently producing a cyanogen halide with suppressed side effects, and a method for producing a high-purity cyanate ester compound at a high yield includes contacting a halogen molecule with an aqueous solution containing hydrogen cyanide and/or a metal cyanide, so that the hydrogen cyanide and/or the metal cyanide is allowed to react with the halogen molecule in the reaction solution to obtain the cyanogen halide, wherein more than 1 mole of the hydrogen cyanide or the metal cyanide is used based on 1 mole of the halogen molecule, and when an amount of substance of an unreacted hydrogen cyanide or an unreacted metal cyanide is defined as mole (A) and an amount of substance of the generated cyanogen halide is defined as mole (B), the reaction is terminated in a state in which (A):(A)+(B) is between 0.00009:1 and 0.2:1.

Previous authors [i] have established the fact that introducing hydroxyl groups into the adamantane framework broadens the scope of antiviralactivity as well as reduces toxicity. For example, 3,5-dimethyl-7-ethyladamantanol-i exhibits pronounced activity with respect to herpes, influenza and vaccine viruses [2]. It might be expected that changing the lipophilic capacity of the skeletal fragment when
