Synthesis and Characterization of Compounds Rink amide resin (Chem-Impex Int’l. .. Inc.), backbone amide linker (BAL) resin (Advanced Chemtech), N-αFmoc-protected amino acids (Novabiochem, Combi-Blocks, or Advanced Chemtech), monoethyl fumarate (Sigma-Aldrich) were used as received. (2S,3S)-3-(ethoxycarbonyl)oxirane-2-carboxylic acid (used for the synthesis of 8c) was synthesized according to published procedures.1 All compounds were prepared by standard Fmoc-based solid-phase peptide synthesis using either a rink amide linker or BAL.3 Cleavage from the resin and deprotection of peptides were achieved in TFA-H2OTIPS (95:2.5:2.5) after stirring for up to 3 h. Following filtration, mixtures were concentrated and the peptides were precipitated and washed several times with diethyl ether.
