Question
Chapter 26.15, Problem 23P
Interpretation Introduction
Interpretation:
The structure of the urea that is produced in the coupling reaction of a protected amino acid and a carboxylic acid with EDCI is to be determined.
Concept Introduction:
Carbodiimides are used in peptide synthesis as a dehydrating agent.
Carbodiimides thereby, forms the peptide (amide) linkage between the two amino acids.
