[reaction: see text] A new and versatile 4-alkoxy-2-hydroxybenzaldehyde (AHB) linker for solid-phase syntheses is described. Acylation of the polymer-bound secondary amine obtained from reductive amination of the aldehyde in the AHB linker showed good reactivity. Following acylation of the phenolic hydroxyl group, the resulting carboxamide resin was stable to treatment with 95% TFA. The O-acyl functional
