The isomerisation of a number of 2-aryl-2-hydroxyadamantanes 1a-h in trifluoroacetic acid is proposed as a good method for preparing the (Z) and (E) stereoisomers of 2-aryl-5-hydroxyadamantanes, 2a-h and 3a-h. Predominant formation of (Z)-isomers 2a -j is observed in all cases. The influence on the stereoselectivity and rate of the nature of the substituents on the aromatic ring, temperature, and time of the reaction is described.
