Abstract:
Disclosed is a configurational stereoisomer, named enantiomer E 1 , of flocoumafen, the enantiomer E 1  having, by chromatographic analysis of flocoumafen performed under particular conditions, a retention time t 1  having a value such that t 1 <t 2 <t 3 <t 4 ; t 2 , t 3  and t 4  representing the retention times of the configurational stereoisomers of flocoumafen different from the enantiomer E 1 , the analysis being performed at a temperature of 23.5° C.

Claim (Index 11):
Chromatographic process for obtaining said enantiomer E 1  according to  claim 1 , in which:\n a high-pressure liquid chromatography column of dimensions 150\u00d72 mm, and comprising a chiral stationary phase constituted of particles of tris(4-chloro-3-methylphenyl carbamate) cellulose, is chosen, said particles having a mean size of 3 \u03bcm and having a mean pore size of 1000 \u212b; a mixture formed from acetonitrile (A) and water comprising 0.1% by volume of formic acid (B), with an A/B volume ratio of 92/8 and with a flow rate of the liquid mobile phase in the chromatography column of 0.25 mL/minute, is chosen as liquid mobile phase; separation of the configurational stereoisomers of flocoumafen is performed at room temperature, during which: a liquid composition comprising said enantiomer E 1  is introduced into the top of the chromatography column; and then the liquid composition is entrained with the mobile phase in the chromatography column under conditions suitable for separating the configurational stereoisomers of flocoumafen, and a fraction of the mobile phase comprising said enantiomer E 1  with a retention time t 1  having a value such that t 1 <t 2 <t 3 <t 4 ; t 2 , t 3  and t 4  representing the retention times of each of the configurational stereoisomers of flocoumafen different from said enantiomer E 1 , is collected separately from said enantiomer E 4  of retention time t 4 ; and the liquid mobile phase of said fraction is removed so as to obtain said enantiomer E 1 .
