| Chloromethyl Polystyrene | The Merrifield resin has in the past been the standard support for the synthesis of peptide acids by Boc strategy. Originally, the cesium salt of a protected amino acid was anchored to the chloromethyl support via nucleophilic displacement of chlorine. Although, Me4N salts, sodium salts in THF with Bu4NF catalysis and more recently zinc salts in EtOH have also been used. Cleavage is normally effected by treatment with HF or trifluoromethanesulfonic acid or by hydrogenolysis, alcohols can be released by using diisobutylaluminium hydride or LiBH4. For cleavage scavengers may be required. Uses: New isomeric trialkoxybenzylamine resins have been developed by coupling phthalimidomethyl-3,5-dimethoxyphenols to this resin followed by subsequent treatment with hydrazine, which allows dcc coupling with the carboxyl function of amino acids or peptides. the addition of alcohols can be performed by heating the corresponding potassium or sodium alkoxide and the resin in dmf. reductive cleavage of. Group: Merrifield resins. Alternative Names: Merrifield Resin. CAS No. 55844-94-5. Pack Sizes: 25g, 100g. |  |
