Abstract

The method of preparation of 3<a>-hydroxy-5-diamantanones of general formula I, where X means H, OH, CH2OH, COOH, consists in the fact that mineral acids are let to treat lactone of 4-hydroxytetracyclo-/7, 3, 1, 0<2>,70<6>, 11/-12-carboxylic acid of general formula II, where X means H, OH, CH2OH, COOH at a temperature of 40 to 200 degrees C, optimally from 100 to 110 degrees C for a period of 1 to 20 hours, optimally from 4 to 8 hours at molar ratio of lactone : mineral acid ranging from 1:2 to 1:100, optimally from 1:10 to 1:20. The 3<a>-hydroxy-5-diamantanone belongs to the group of synthetic immunostimulants.<IMAGE>
