A library of N-phenolic and N-catecholic dehydroaminoacidderivatives was prepared using an innovative synthetic strategy that involves mild reaction conditions and simple work-up procedures. The method comprises coupling of phenolic or catecholic acids with β-hydroxyamino acids followed by tert-butyloxycarbonylation of all hydroxyl groups using tert-butyldicarbonate and 4-dimethylaminopyridine as
