A subject of the invention is the use of a salt with a dedicated task of formula (I):
A
+
-L-R—OY, X
−
as soluble support for peptide synthesis, in which:
X
−
represents a functional or non-functional anion,
Y represents either a hydrogen atom, or a —COOR
1
group, R
1
representing in particular an alkyl group comprising 1 to 20 carbon atoms,
A
+
represents a cationic entity,
L represents an arm, in particular an alkyl group of 3 to 20 carbon atoms,
R represents in particular a group of formula —C(R
a
)(R
b
)—, R
a
and R
b
representing independently of one another in particular a hydrogen or an alkyl group, comprising 1 to 20 carbon atoms.
Taskspecific ionic liquids and onium salts have been used as solublesupports for peptide synthesis. These new supports combine easy monitoring, high loading capacities, large scale preparation, and homogeneous kinetics characteristics while keeping advantages of solid-phase synthesis including easy purification and workup. Careful structural design of these supports allowed for fine tuning of physical
