Claim 3:
4. The process according to claim 1, wherein the compound(s) of formula (I) and/or (II) are chosen from those of formulae (I′) or (II′):, , wherein in formulae (I′) and (II′):
Z″1 is chosen from an oxygen atom or a group —N(R″6)—;
with the proviso that when Z″1 represents —N(R″6)—, then R″1 and R″6 may form, together with the nitrogen atom to which they are attached, an optionally substituted, 5- or 6-membered, saturated, unsaturated or aromatic heterocycle;

R″1 represents a C1-C6 alkyl radical, optionally interrupted with one or more non-adjacent oxygen atoms, and/or optionally substituted with:
a hydroxyl radical,
a di(C1-C4)alkylamino radical, or
a heterocycle optionally substituted with one or more C1-C4 alkyl and/or hydroxyl radicals and chosen selected from pyrrolidine, piperidine, morpholine, piperazine, or imidazole;

R″6 represents:
a hydrogen atom, or
a C1-C10 alkyl radical optionally substituted with a hydroxyl radical; and

R″2, R″3, R″4, and R″5 each independently represent:
a hydrogen atom, or
a C1-C4 alkyl radical.
