T11.1. A student was provided with the following compounds: (i) N-acetyl-L-Aspartic acid (ii)
tert-butyl amine and (iii) coupling agent N,N'-dicyclohexylcarbodiimide (DCC) – to create
peptide(s). The synthesis was successfully completed at 100% conversion, where a 2:1 ratio of the
amine to amino acid was used and all possible peptide bonds were formed. If partial racemization
also took place during the synthesis, how many types of product(s) can the student possibly obtain
from the reaction?
