| 2 | 8 | LA | (s)-(−)[DPTAC][LA] |
| 3 | 9 | LA | c[DPTAC][LA]ee:31% |
| 4 | 10 | LA | c[DPTAC][LA]ee:48% |

a
All these DESs were prepared using a 1:2 HBA/HBD stoichiometric ratio.
b
rac: DESs prepared with the racemic form of the corresponding HBA.
c
ee: enantiomeric excess percentage corresponding to the HBA used to prepare the corresponding DES.
d
These DESs were also prepared with two different stoichiometric ratios (1:1 and 1:3 HBA/HBD).
