title: One-pot high-throughput synthesis of beta-turn cyclic peptidomimetics via "volatilizable" supports.
abstract: A promising method for the high-throughput synthesis of linear C-hydroxyalkylamido peptidomimetics and beta-turn cyclic peptidomimetics via "volatilizable" aminoalkyl functionalized silica gels is presented. Boc amino acids and carboxylic acids were coupled on functionalized aminoalkyl silica gels using a standard DIC/HOBt coupling protocol. After peptide synthesis, the resin bound peptide was cleaved using a two-step process to obtain the linear C-hydroxyalkylamido peptidomimetics. Beta-turn cyclic peptidomimetics were generated by intramolecular S(N)Ar cyclization in an aqueous solution. Both the linear and the cyclic peptidomimetics were obtained with good to excellent yields and purities through a "one-pot" reaction.
