Nitrogenated compounds react with hypochlorous acid yielding N-chloro
compounds. In principle, alpha-amino acids chlorination may take place
on the oxygen of the carboxylic group or on the nitrogen of the amino
group. In this framework, we discuss the different reactivities of ni
trogen and oxygen towards chlorine, and come to the conclusion that th
e nitrogen is the preferred reaction site in alpha-amino acids chlorin
ation. (C) 1994 John Wiley & Sons, Inc.
