The N-dichloroacetyl derivatives of DL-serine and DL-threonine were prepared by the Schotten–Baumann reaction from the amino acids and dichloroacetyl chloride. Negative ninhydrin tests coupled with elementary analyses indicated that only the amino group was acylated. The esterderivatives of these compounds were prepared either by esterification of the N-dichloroacetyl-DL-amino acid with diazomethane
