Résumé
Phthalimido-alkanol solid supports were rapidly prepared from solid supported phthalic anhydride and amino alcohol condensation induced by microwaves. These supports were used to synthesize 5'-fluorescent 3'-aminoalkyl oligodeoxynucleotides allowing a two-step deprotection necessary to avoid aminolink alkylation. After conversion into an NHS derivative using dissuccinimidyl suberate and an optimized isolation, they were conjugated with a protein.
