method for the production of intermediates diastereoselektives usable for peptidderivatensynthese.

摘要

A diastereoselective process for the preparation of compounds of formula CHEM (wherein R and R1 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.
