Papain-catalyzed esterification of N(α)-protected amino acids and dipeptides with ethanol in different organic systems

The papain-catalyzed esterification of N(α)-protected amino acids and dipeptides with ethanol in mostly hydrophobic organic solvent systems containing low amounts of water has been investigated. The influence of various parameters, such as the amount of added water, reaction time, temperature and pH of added buffer, on the yield of ester was studied first on the model substrate Z-Ala. The optimized reaction conditions were then used for esterification of a series of N(α)-protected amino acids and dipeptides.
