diastereoselective process for the preparation of useful intermediates for the synthesis of peptide derivatives.

摘要

A PROCESS diastereoselective FOR THE PREPARATION OF COMPONENTS OF FORMULA (I) WHERE RY R1 have the meanings REPORTED IN THE SPECIFICATION AND Asterisks SHOWN asymmetric carbons starting from the corresponding N - PROTECTED 2 - AMINO - 3 - ARYL - PROPANE - 1 - OL described. INGREDIENTS OF FORMULA I are intermediates useful for the pharmacologically active peptide synthesis.
