There are 20 commonly occurring amino acids from which all proteins are derived, although many other less common amino acids have been isolated from natural sources. Valine is one of the 20 common amino acids, and it was used as a starting material in the laboratory synthesis of an uncommon amino acid. During one of the steps in the synthesis, compound 1 was treated with HBr under conditions that favor radical addition, giving stereoisomers 2 and 3. H. OCH3 HBr 2 + 3 hv (S)-valine Draw the structures of 2 and 3.
