Abstract:

The method for the enantioseparation of ferroence derivatives, four derivatives with single chirality and three derivatives with double chiralities containing centre and face chirality, on chiral stationary phases, namely Chiralpak IC (cellulose-tris(3,5-dichlorobenzene carbamate)) and Chiralpak IE3 (amylose-tris(3,5-dichlorobenzene carbamate)), was investigated. We found that the three derivatives of the four chiral ferroence derivatives with single chirality can be baseline separated on Chiralpak IE3; another one can be baseline separated on Chiralpak IC. Meanwhile, the three chiral ferroence derivatives with double chiralities can be baseline separated on Chiralpak IC. The research shows that the both kinds of chiral stationary phases exhibited high enantiomeric recognition capability to the enantiomers of the chiral ferroence derivatives. This two chiral stationary phases exhibited complementary selectivities in the enantioseparation of chiral ferroence derivatives. This study provides a reference method for the enantioseparation of chiral ferroence derivatives.
