A diastereoselective process for the preparation of compounds of formula ##STR1## (wherein R and R.sub.1 have the meanings reported in the specification and the asterisks show the asymmetric carbon atoms) starting from the corresponding N-protected 2-amino-3-aryl-propan-1-ol is described. The compounds of formula I are intermediates useful for the synthesis of pharmacologically active peptides.
描述了一种非对映选择性过程,用于制备通式##STR1##的化合物(其中R和R₁具有说明书中报告的含义,星号表示不对称碳原子),该过程从相应的N-保护的2-
氨基-3-芳基丙-1-醇开始。通式I的化合物是合成具有药理活性的肽的有用中间体。
