11. For example, DMDO will oxidize primary amines to nitro compounds and sulfides to sulfoxides. 12. Reaction with ammonia give primary amines . 13. It is the simplest primary amine . 14. This process is repeated again at C4 to form a second primary amine ( 4a ). 15. The reaction is typically run under protic or Lewis acidic conditions, with a primary amine . 16. Sample proteins are first blocked by reduction and alkylation at their primary amines before endopeptidase treatment. 17. The compound is used as a reagent for the preparation of primary amines from alkyl halides. 18. One of these is in the asymmetric hydrogenation of N-unfunctionalized imines to give primary amines . 19. The molecule is both a primary amine and a primary alcohol ( due to a hydroxyl group ). 20. This ketone is then formed into a primary amine group through PLP and glutamine transamination ( 3a ).
