A solid-phase synthesis of polyamines on 4-alkoxytrityl chloride resin 5 is described. By alkylation of nitrobenzenesulfonamide 8 with alkyl halide 7 prepared from the resin 5, spermine bound resin 10 was efficiently synthesized. Condensation of 10 and tyrosine derivative followed by deprotection and cleavage from the resin afforded highly pure philanthotoxin-343 (4).
