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 (Tetrahedron 1997, 53, 1151-1156). 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.
