    • The cyclodimer and higher-order oligomers were easily separated by HPLC from the cyclomonomer in most of the samples, and their identification was confirmed by MS/MS. Also, to confirm the assignment of cyclodimers two examples were synthesized independently by cyclization of linear 12- or 14-mer linear precursors. In both cases, their LCMS profiles were identical to those of the cyclodimers found in the original library.

    • For scaffolds with high (av 91%) and low (av 23%) yields of cyclomonomer, the average extent of C-terminal racemization was 10 ± 4.8% and 7.4 ± 1.2%, respectively.

    • note
    • In every case the mass of the major product correlated with the mass of one of the sequences expected for that scaffold. Amino acid analysis with Marfey's reagent was performed on 18 samples and confirmed the stereochemistry and identities of the amino acids. The results of Marfey's test correlated in each case with the mass obtained from LCMS analysis.
