The syntheses of N-protected dipeptide acids using alkaline earth metal (Mg, Ca, and Ba) carboxylates of an amino acid in organic solvents were investigated. It was found that amino acid calcium carboxylates are the most effective among the carboxylates of the amino acids tested for coupling with active esters of Boc-Ala-OH in organic solvents. The coupling of Boc-Ala-ONp or Boc-Ala-ONSu with amino acid calcium carboxylates in DMF gave the desired N-protected dipeptide acids in high yields (92-100%).

The design and synthesis of peptide-2′-deoxythymidine-5′-O- monophosphate conjugates as potential active delivery systems for nucleotides into auxotrophic E. coli strains is presented. A series of oligopeptides were allowed to react with 5′-O-(dibenzylphosphate)-2′-deoxythymidine or its suitably 3′-derivatized analogues to give the relevant peptide-nucleotide adducts, by the formation of a biolabile chemical connection. Using strategies based on the principles of orthogonal protection and activation, rational variations were made to the linker and the peptide moiety in order to tune the metabolic stability of the conjugates.
