Description

General description

This support consists of MBHA resin functionalized with Riniker′s hyperacid-labile 4-hydroxymethyl-3-methoxyphenoxybutyric acid linker ^[1].This hyperacid-sensitive resin is a useful tool for the Fmoc SPPS of protected peptide acid fragments. Attachment of carboxylic acids is normally achieved by DMAP catalyzed esterification with the appropriate symmetrical anhydride, or by using 2,6-dichlorobenzoylchloride/pyridine ^[2] or MSNT/Melm activation ^[3,4,5].Detachment of these functionalities can be effected by treatment with 1-5% TFA in DCM.
