METHOD OF OBTAINING 1-HYDROXYADAMANTHAN-4-ON Russian patent published in 2008 - IPC C07C49/513 C07C45/64

Abstract RU 2342358 C2

FIELD: chemistry.

SUBSTANCE: claimed invention relates to method of obtaining 1-hydroxyadamanthan-4-on, which is immuno-stimulating means, efficient for treatment of limbs vascular system diseases of autoimmune genesis, chronic stomatitis, herpes, etc. Method lies in catalytic oxidation of adamanthon-2. Here as oxidant agent, hydrobromous acid is used, which is generated in situ from carbon tetrabromide and water, and oxidation is performed in presence of catalysts - compounds of molybdenum Mo(CO)₆ or tungsten W(CO)_6, with molar ratio[Mo(CO)₆ or W(CO)₆]: [adamanthon-2]:[CBr₄]:[H₂O]=1:100:100:1000-4000 at temperature 140-160°C during 6-10 hours.

EFFECT: obtaining 1-hydroxyadamanthan-4-on with high output, with simplification and cheapening technology.
