The reaction of lithium salts of dialkyl methylphosphonates with suitably protected amino acid methyl esters at low temperature, followed by removal of protecting groups in the presence of trimethylsilyl bromide provides an efficient method for the synthesis of the titled compounds.

The dipeptide D-alanyl-D-alanine is an essential precursor of bacterial peptidoglycan; thus, blocking its formation is a possible target for the design of novel antibacterial agents. The synthesis of this dipeptide by bacterial D-alanine:D-alanineligase requires ATP. In analogy with glutamine synthetase, we hypothesized a mechanism for this enzyme involving the intermediacy of D-alanyl phosphate.
