From benzyloxycarbonyl (Z), tert-butoxycarbonyl (Boc) and allyloxycarbonyl (Aloc) protected dipeptide heptyl esters the N-terminal protecting groups can be removed by chemical methods and the C-terminal COOH function is liberated selectively by enzymatic hydrolysis with a lipase from Rhizopus niveus.
