(a)
Interpretation: The mechanism for the reaction that adds an Fmoc group to an amino acid under the given conditions is to be drawn.
Concept introduction: Peptide linkage is formed between the amino group of one amino acid and the carboxyl group of other amino acid with the loss of water molecule. Amino acids are naturally occurring compounds in which the amino group is present on the alpha carbon of carboxyl group. The full form of Fmoc is fluorenylmethyloxycarbonyl chloride. It introduces Fmoc group which protects the

- One of the ways in which an L a-amino acid can be synthesized is to carry out an Sy2 reaction between an a-bromo acid and ammonia. (The wavy line indicates that the bond could be a dash or a wedge.) Draw the stereoisomer of the a-bromo acid that would be necessary Br. H3N.
