β¦ Synopsis
A novel linkage for the solid-phase synthesis of hydroxamic acids is described. The linkage is stable to all reagents commonly used in Fmoc peptide synthsis. Cleavage is induced by treatment with trifluoroacetie acid, providing hydroxamic acids in high purity and good yields.

The synthesis of peptide hydroxamic acids has been performed on a solid support. A carboxyl group of a peptide synthesized on/xTa-methylbenzhydrylaminΒ’ (pMBHA) resin was converted to a hydroxamate functional group by condensing with NH2OBzl, which was found preferable to NH2OtBu or NH2OTrt. The hydr
The solid-phase synthesis of a nucleoside hydroxamic acid is accomplished by the Pd(0) cross-coupling of 5-iodouridine and an O-linked hydroxylamine alkyne bound to 2chlorotrityl chloride polystyrene resin.
