Novel alcohols of the formula <IMAGE> I wherein Ra is azido or phthalimido, R4 is alkyl, cycloalkyl, cycloalkylalkyl, aryl or aralkyl, R7 and R8 together are a trimethylene or tetramethylene group which is optionally substituted by hydroxy, alkoxycarbonylamino or acylamino or in which one -CH2- group is replaced by -NH-, -N(alkoxycarbonyl)-, -N(acyl)- or -S- or which carries a fused cycloalkane, aromatic or heteroaromatic ring, and R9 is alkoxycarbonyl, monoalkylcarbamoyl, monoaralkylcarbamoyl, monoarylcarbamoyl or a group of the formula <IMAGE> in which R10 and R11 each is alkyl, are described along with a process for their manufacture. These alcohols are useful as intermediates, for example in the manufacture of amino acid derivatives having antiviral activity.
