A retrosynthetic analysis to plan a synthesis of valine from 3-methylbutanoic acid is to be discussed and equations for the synthesis are to be written. Concept Introduction: Amino acids can be synthesized by the reaction of an α-halo carboxylic acid with ammonia. This is called as nucleophilic substitution reaction. α-halo carboxylic acid can be prepared by the reaction of halogens with the carboxylic acids. Phosphorus tribromide is used to promote the halogenation in this reaction.
