Combinatorial solid-phase synthesis of hapalosin mimetics

Research output: Contribution to journalJournal articleResearchpeer-review

The solid-phase synthesis of a small library of mimetics of the cyclic depsipeptide hapalosin is described. 3-Amino-4-hydroxy-5-nitrobenzoic acid was anchored through the anilino moiety to a backbone amide linker (BAL) handle support. Using chemoselective reactions and without the need for protecting group manipulations, the benzoic acid group was first amidated, then the aniline nitrogen was acylated, and finally the nitro group was reduced to an amine and acylated or reductively alkylated, to generate a 12-member library.
