Selective Catalysis of Ester Aminolysis: An Approach to Peptide Active Esters

Model studies have been carried out in which the Kaiser-DeGrado procedure for solid-phase synthesis has been combined with the use of reactants with a latent activation feature as a potential route to peptide active esters.The rates of reaction of the 4-(
