    Notizen: The choice of a polymeric support is a key factor for the success of solid-phase methods for syntheses of organic compounds and biomolecules such as peptides and oligonucleotides. Classical Merrifield solid-phase peptide synthesis (SPPS), performed on low cross-linked hydrophobic polystyrene (PS) beads, sometimes suffers from sequence-dependent coupling difficulties. The concept of incorporating polyethylene glycol (PEG) into supports for solid-phase synthesis represents a successful approach to alleviating such problems. Previous reports from our laboratories have shown the advantages of “low-load” PEG-PS (0.15-0.25 mmol/g) for SPPS. Herein, we demonstrate that the beneficial aspects of the PEG-PS concept can be extended with resins that have higher loadings (0.3-0.5 mmol/g). © 1999 John Wiley & Sons, Inc.

    Notizen: The solid-phase synthesis of small organic molecules has received renewed attention since the first reports of the polymer-supported synthesis of compounds of therapeutic interest. Solid-phase synthesis is now a key component of the high-throughput synthesis and screening approach to drug discovery. The recent rapid growth in the number of organic transformations that have been successfully demonstrated on solid supports has involved both the use of the established amine, halide, and hydroxyl supports developed originally for peptide synthesis, and the design and synthesis of new supports to permit the anchoring and releasing of other functional groups. In this article, resins and linkers are subdivided according to the functional group on the solid support to which the first building block is anchored. The chemistry of these supports is illustrated by a relatively small but representative selection from the many recent examples of potential therapeutic agents synthesized on solid supports. © 1999 John Wiley & Sons, Inc.
