Stereoselective Syntheses of Peptide Derivatives with 2‐Acetamido‐3,4,6‐tri‐<i>O</i>‐acetyl‐1‐amino‐2‐deoxy‐β‐<scp>D</scp>‐glucopyranose by Four‐Component Condensation

Abstract

Diastereoisomeric excesses greater than 99% are obtained for the majority of the stereoselective four-component condensations (a), if the amino glucopyranose 1 is used as the sugar component Y-NH2.
