Abstract
Flutriafol, a globally utilized triazole fungicide in agriculture, is typically applied as a racemic mixture, but its enantiomers differ in bioactivity and environmental impact. The synthesis of flutriafol enantiomers is critically dependent on chiral precursors: 2,2-bisaryl-substituted oxirane [(2-fluorophenyl)-2-(4-fluorophenyl)oxirane, 1a] and 1,2-diol [1-(2-fluorophenyl)-1-(4-fluorophenyl)ethane-1,2-diol, 1b]. Here, we engineered a Rhodotorula paludigensis epoxide hydrolase (RpEH), obtaining mutant Escherichia coli/RpehH336W/L360F with a 6.4-fold enhanced enantiomeric ratio (E) from 5.5 to 35.4. This enabled a gram-scale resolution of rac-1a by E. coli/RpehH336W/L360F, producing (S)-1a (98.2% ees) and (R)-1b (75.0% eep) with 44.3 and 55.7% analytical yields, respectively. As follows, chiral (S)-flutriafol (98.2% ee) and (R)-flutriafol (75.0% ee) were easily synthesized by a one-step chemocatalytic process from (S)-1a and a two-step chemocatalytic process from (R)-1b, respectively. This chemoenzymatic approach offers a superior alternative for the asymmetric synthesis of flutriafol enantiomers. Furthermore, molecular dynamics simulations revealed insight into the enantioselectivity improvement of RpEH toward bulky 2,2-bisaryl-substituted oxirane 1a.

Abstract
The first asymmetric synthesis of (R,R)-clemastine (1) has been accomplished by the coupling of (R)-tertiary alcohol 2 and (R)-chloroethylpyrrolidine 3 via O-alkylation. (R)-Tertiary alcohol 2 was synthesized by stereoselective alkylation of chiral α-benzyloxy ketone with Grignard reagent via chelation-controlled 1,4-asymmetric induction. In the reaction, chiral benzyl group acts as a chiral auxiliary as well as a protecting group. (R)-Chloroethylpyrrolidine 3 was prepared by asymmetric transformation starting with L-homoserine lactone, in which racemization-minimized N-allylation and ring-closing metathesis were involved as key steps.

Abstract
The stereoselective dissipation of flutriafol and tebuconazole in grape had been studied. A simple and sensitive method for determination of flutriafol and tebuconazole enantiomers in grape was developed by high-performance liquid chromatography on a cellulose tris(3-chloro-4-methylphenylcarbamate) column. The limits of quantification for flutriafol and tebuconazole in grape were 0.033 and 0.043 mg kg(-1), respectively. The dissipations of flutriafol and tebuconazole stereoisomers in grape followed first-order kinetics (R (2) > 0.93). The stereoisomers of flutriafol and tebuconazole were enantioselectively degraded in grape, and tebuconazole was more enantioselective than flutriafol. The half-life of (-)-tebuconazole was 5.2 days and shorter than (+)-tebuconazole with half-life of 6.4 days. The (-)-flutriafol was also preferentially degraded in grape, the half-lives of which were 6.59 and 6.98 days for (-) and (+)-flutriafol, respectively. The enantiomeric ratio value of the two fungicides was nearly 1.0 at the 1st day and increased to 1.143 for flutriafol and 2.015 for tebuconazole at the 28th day. The stereoselective dissipations could provide a reference to fully evaluate the risks of two important chiral triazole fungicides.

Abstract
A novel and effective method for enantioselective determination of flutriafol enantiomers in food and environmental matrices (cucumber, tomato, grape, pear, wheat, soil, and water) has been developed. The (R)-(-)-flutriafol was first eluted and measured from electronic circular dichroism spectra using a cellulose tris(3-chloro-4-methyl phenyl carbamate) chiral column. The mean recoveries from the samples ranged from 82.9% to 103.4%, with intraday relative standard deviations (RSD) of 2.2-8.3% and interday RSD of 3.4-7.9%. Good linearity (R(2) ≥ 0.9989) was obtained for all analytes matrix calibration curves within the range of 0.1-10 mg/kg. The limits of detection for two enantiomers in the seven matrices were all below 0.015 mg/kg. The results show that the proposed method is convenient and reliable for the enantioselective detection of the flutriafol in the real samples and is applicable to the environmental stereochemistry of flutriafol in food and environmental matrices.

Abstract
The stereoselective pharmacokinetics of flutriafol were investigated in male and female adult Japanese white rabbits. Following intravenous administration of rac-flutriafol to rabbits at 5 mg/kg (bd wt), the concentrations of the enantiomers in plasma were determined by a HLPC-UV method using a CDMPC-CSP chiral column. R-Flutriafol exhibited a shorter distribution half-life but a longer elimination half-life than the S-isomer. In female rabbits, the distribution half-lives of R- and S-flutriafol were found to be 0.09 and 0.18 h, respectively, significantly shorter than those in male rabbits, but the volume of distribution and elimination half-life for flutriafol enantiomers in both sexes of rabbit showed no significant differences. Female rabbits had a higher clearance for both flutriafol enantiomers. The protein binding value was high for both isomers, with enantioselectivity, but no gender difference. It was an important factor in modulating the disposition of flutriafol. Flutriafol concentrations in kidney, liver, fat, and lung were higher than in other tissues at 10 h after administration, and the concentrations of R-flutriafol were higher in all tissues than those of its antipode. However, gender difference in flutriafol residues in tissues was not observed. It is concluded that the stereoselectivity of flutriafol on distribution and elimination in rabbits mainly depends upon gender.
