  • Patent number: 4914151
    Abstract: The present invention relates to a novel polymeric carrier, a process for its production and its use for the preparation of peptides and their intermediates. The process comprises reacting chloromethylated polystyrene (cross-linked with divinylbenzene) with a 4-hydroxy-2-substituted-benzyl alcohol (linker), attaching .alpha.-amino acids with amino and side-chain protection to the carrier thus obtained, and building up a peptide according to the method known in the field of solid phase peptide synthesis (SPPS). The method allows removal of intermediates or final products under extremely mild acidic conditions giving products in high state of purity and yield. The 2-substituent consists of an electron donating group, such as methoxy.
