21. Enolate Chemistry:Reactions at the Alpha-Carbon
Tautomerization
A student tried to synthesize the octapeptide Thr-Pro-Glu-His-Tyr-Asn-Ile-Gln in the lab and got a yield of 85% for the addition of each amino acid to the chain. What is the overall yield for the synthesis of Thr-Pro-Glu-His-Tyr-Asn-Ile-Gln?
