Two methods for the synthesis of N-(2-chloroethyl)glycine and-DL-alanine esters are proposed: 1) reductive amination of the C=O group of glyoxilic or pyruvic acids upon treatment with 2-chloroethylamine and sodium cyanoborohydride in methanol and 2) alkylation of 2-chloroethylamine with α-haloalkanoic acid esters in K2CO3-MeCN two-phase system.

A new synthesis of Boc-protected cyclic amino acids is described as an application of an unreported method of lithium diisopropylamide-induced cyclisation of omega-chloro carboxylic acids containing a protected amine function in the chain.
