Chapter 28, Problem 36DSP

Interpretation Introduction

Interpretation:

The polymer-containing product of the given reaction is to be identified.

Concept Introduction:

In the presence of $\text{N,N'-dicyclohexylcarbodiimide }\left(\text{DCCI}\right)$, the amine and the compound containing carboxylic acid group form an amide. It takes place due to the formation of a peptide bond between the nitrogen and carbon protected amino acids.

The $\text{N,N'-dicyclohexylcarbodiimide }\left(\text{DCCI}\right)$ works as a dehydrating agent.

The bond formed between nitrogen atom of one amino acid and the carbonyl carbon of the other amino acid is called peptide bond $\left(\text{R-CO-N<}\right)$.
