The present invention relates to a supported oxidation reactant of formula (I): R-[Met(O)k]n-X- (I) in which: - R represents a hydrogen atom or an amine function-protecting group, -[Met(O)] represents an oxidized methionine residue of formula - k is 1 or 2 - represents a solid or soluble support used in organic synthesis, - X represents a radical derived from a function of the type amine or hydroxyl, or halogeno, capable of anchoring methionine, it being understood that this function capable of anchoring methionine can be separated from the support by means of a functionalized arm or a spacer, and - n is an integer greater than or equal to 1. The invention also relates to the use of a supported oxidation reactant of formula (I), for the formation of intramolecular disulfide bridges, in particular in peptides and/or proteins.

The present invention relates to a pipecolic linker and its use as a solid-phase linker in organic synthesis. Said pipecolic solid-phase linker may be used for coupling functional groups chosen between primary amines, secondary amines, aromatic amines, alcohols, phenols and thiols. In particular, said pipecolic solid-phase linker may be used for peptide or pseudopeptide synthesis, such as the reverse N to C peptide synthesis or the retro-inverso peptide synthesis, or for the synthesis of small organic molecules.
