Abstract: A symposium report. Protected peptides were synthesized using 9-fluorenylmethoxycarbonyl (Fmoc) amino acids and the acid labile 2-chlorotrityl and the multidetachable 2-chlorotrityl-Rink-linker resins. After their cleavage from the resins, the obtained peptides were esterified in solution with 2-chlorotrityl chloride and DIEA. The obtained esters, were deprotected at the N-terminal function, condensed to larger peptides and reesterified on the resin after the selective removal of the chlorotrityl function. In cases where mixtures of protected peptides were used for the esterification with the trityl-resin, a competition was observed among them for the occupation of the most favourable positions of the resin. Mixtures of protected peptides were also used in fragment condensations in order to evaluate the best possible conditions for the preparation of long-chain peptide libraries.
