Using the new compound N-Fmoc-hydroxylamine 1 we have generated a facile route to a high loading, acid labile solid-phase resin bearing a hydroxylamine linker. The novel N-Fmoc-aminooxy-2-chlorotrityl polystyrene 2 showed generic utility for the construction of hydroxamic acids, including peptidyl hydroxamic acids. (C) 1997 Elsevier Science Ltd.

Polymer-supported N-benzyloxy-2-nitrobenzenesulfonamides 1 were N-alkylated using three different routes: via Fukuyama reaction with alcohols, by N-alkylation with alkylbromides, and by Michael addition reaction with alpha, beta-unsaturated carbonyl compounds. The N-alkylated products prepared on the linker 1b were obtained in excellent purity and yield. The 2-nitrobenzenesulfonyl (Nos) group was cleaved under mild conditions to yield polymer-supported N-alkylated benzyloxyamines. Acylation by carboxylic acids and cleavage with TFA yielded N-alkyl hydroxamic acids. (C) 2004 Elsevier Ltd. All rights reserved.
