prepared and applied to solid-phase peptide synthesis using 9-fluorenylmethyloxycarbonyl (Fmoc) for Nα-amino protection and tert-butyl ethers, esters, and urethanes for side-chain protection. Otherwise fully protected peptide acids, which are needed for segment condensation studies, were obtained in excellent yields and purities by cleavage of the resultant tris(alkoxy)benzyl ester anchoring linkage with
