The 2,5-diaryl-2-adamantanol and 2-(3-alkyl-1-adamantyl)-2-alkanol were found to produce the corresponding 2,5-diayl-7- and 3,5-dialkyl-1-adamantanols in trifluoroacetic acid with high selectivity. This synthetic methodology is proposed as a perspective approach to 2,5,7- and 1,3,5-trisubstituted adamantanes.

bromine-free, direct C–H bond amidations we have synthesized a large variety of adamantane amides. Depending on the precursors used these amides directly yield pharmaceutically active aminoadamantanes or γ-aminoadamantanecarboxylic acids after hydrolytic cleavage. Theserigid analogues of γ-aminobutyric acid (GABA) were protected at the C- and N-termini and we synthesized a number of peptides incorporating γ-a
The present invention provides novel pyrimidine amines of formula I which are potent inhibitors of spleen tyrosine kinase, and are useful in the treatment and prevention of diseases mediated by said enzyme, such as asthma, COPD, rheumatoid arthritis and cancer.
