transformation of the (S,S)-2-fluorocycloalkyl N-phenylcarbamates is not diastereoselective giving almost 1:1 mixtures of cis- and trans-4-hydroxyl compounds, the corresponding reactions of the (R,R)-isomers led preferentially to the products trans-hydroxylated in the 4-position. The transformation of the racemic fluorinated six-membered N-phenylcarbamate 3 led to products having a very small enantiomeric
