The Chlorine function in this building block is labile and reactive. Depending on reaction conditions, it is prone to nucleophilic substitution or to elimination. Thus, it is not primarily a building block to permanently introduce 3-Chloroalanine into a peptide, but rather to use the function for further modification such as cyclic peptide ring closure or introduction of Dehydroalanine. However, there are also publications (see below) reporting introduction of 3-Chloroalanine into peptides without elimination.
