Carboxyl groups of amino acids have been protected as 1-adamantyl esters via the amino acid tosylate and dimethyl sulfite. The group is readily cleaved with TFA under mild conditions: Synthesis, 1355 (1996). Has also been applied in blocking the ß-carboxyl group of aspartic acid in peptide synthesis; the 1-adamantyl ester is prepared using DCC-DMAP: J. Chem. Soc., Perkin 1, 2129 (1988). See also Appendix 6.
Thiol groups may also be protected by formation of the thioether in TFA. Cleavage is by means of Hg(II) salts: Chem. Pharm. Bull., 26, 1576 (1978).
Reaction with Hydrogen fluoride pyridine complex, L17117, gives 1-fluoroadamantane, a general method for conversion of sec- and tert-alcohols to fluoroalkanes: Org. Synth. Coll., 6, 628 (1988).
