3. How would you synthesize phenylalanine using Strecker synthesis?
1. Consider the synthesis of the following amino acids: a) write all the steps for the synthesis of valine starting with propane, using the HVZ reaction to make a bromo-acid, which is subsequently laminates. b)Write all the steps for the synthesis of leucine starting with isobutane and using the Gabriel-Malonic Ester reaction. Also, consider: I)how would the L-enantiomer of the amino acid be isolated from the racemic mixture resulting from the above reactions. ii) what would the mechanism be for...
