26% With Aspergillus niger epoxide hydrolases immobilized onto modified Eupergit C; In aq. phosphate buffer; dimethyl sulfoxide; at 25℃; for 3h;pH 6.5;Enzymatic reaction;Kinetics; General procedure: Asymmetric hydrolysis of (R/S)-SO, (R/S)-PO and (R/S)-ECH were examined in a batch type reactor (1.1 cm × 5 cm). To 1.5 mL of 100 mM phosphate buffer (pH = 7.0 for the free and EHIL; pH = 6.5 for EHIF and EHIE), 100 L of the free EH solution (1 mg mL-1) or 30 mg of each immobilized EH was loaded and the mixture kept at 25 C for 2 min. The reaction was initiated by the addition 0.4 mL of each racemic epoxide solution (0.5 M in DMSO). A hundred microliters of aliquots withdrawn at different time intervals (15, 30,60, 90, 120, 180 and 240 min) were mixed with 400 L of diethylether and analyzed by a Shodex ORpak CDC-453 HQ chiral HPLC column (4.6 mm × 150 mm) according to Yildirim et al. [23]. The enantiomers of styrene oxide and their vicinal diols were detected at 220 nm. The enantiomers of propylene oxide, epichlorohydrin and their vicinal diols were detected using a refractive index detector (Shimadzu RID-10A). The optical configurations of remaining epoxides and formed diols were identified by comparing the retention time of these compounds with their optically active standard forms. The enantiomeric excess (ee) values of formed vicinal diol and remaining epoxide were calculated from the equations: eeepoxide=([S-R]epoxide)/([S+R]epoxide) and eediol=([R-S]diol)/([R+S]diol) The enantiomeric ratio values (E) of free and immobilized EHs were calculated from the equation proposed by Chen et al. [27]. E=(Vmax(R)/Km(R))/(Vmax(S)/Km(S)) where Vmax(R) and Km(R) values are maximum velocity and Michealis-Menten constant of free and immobilized EH preparations toward (R)-enantiomer of epoxide and Vmax(S) and Km(S) are corresponding values toward (S)-enantiomer of epoxide.

EXAMPLE 3 This Example shows the conversion of (S)-3-amino-1,2-dihydroxypropane isopropylidene acetal 11 to (S)-1-chloro-2,3-dihydroxypropane 3.
EXAMPLE 2 Sodium periodate (9.31 g) was added slowly to a cooled and stirred solution of 6,6'-dichloro-6,6'-dideoxy-sucrose (5.0 g) in water (250 ml). After stirring at room temperature for 2 hours, the solution was diluted with ethanol (750 ml) and the resulting suspension was stirred at room temperature for a further 2 hours. The suspension was then filtered and the filtrate was concentrated to a syrup (25 ml) which was diluted with water (100 ml). A solution of sodium borohydride (2.04 g) in water (50 ml) was added slowly with cooling to the solution of oxidised product. After the addition, the reaction mixture was stirred at room temperature for 20 hours, and then a few drops of acetic acid were added. Concentration in vacuo at 40 gave a semi-solid mass which was then dissolved in ethyl acetate (AR):ethanol (9:1) and eluted through a column of silica gel. Evaporation of the elude yielded a semi-solid mass (5.1 g). T.l.c. showed that this was a mixture. The components were identified by g.l.c. to be alpha-chlorohydrin, dihydroxyacetone (dimer) and hydroxyacetaldehyde. Chromatography and distillation of the product mixture gave S-3-chloro-1,2-propanediol identical with that obtained in Example 1.

With potassium tert-butylate; acetic acid; In tetrahydrofuran; hexane; water; ethyl acetate; To a solution of 1056 g (3.64 mol) of 2-Methylpropyl (4-bromo-3-fluorophenyl)carbamate in 6.65 L of THF cooled to -15 C. in a 22 L round bottom flask was added a solution of 428 g (4.55 mol, 1.25 equiv.) of lithium t-amylate over 10 min via an addition funnel, maintaining -15 to -12 C. In a separate 5 L flask, a solution of 438 g (4.37 mol, 1.20 equiv.) of (S)-3-chloro-1,2-propanediol in 1.75 L of THF was cooled to -25 C. and treated with a 20% t-BuOK solution in THF (2645 mL, 4.29 mol, 1.18 equiv) over 25 min, resulting in a thick but stirrable slurry. This was allowed to warm to 10 over 75 min and then poured into the 22 L flask containing the carbamate solution. The resulting slurry was allowed to warm from -7 to 7 over 1.5 h, monitoring reaction progress by HPLC. Upon completion (~2.5% each of remaining 2-Methylpropyl (4-bromo-3-fluorophenyl)carbamate and the over addition product) a quench solution composed of 1.05 AcOH and 3.5 L of water was added. The layers were separated. The aqueous layer was back-extracted with 1 L of THF, and the combined organic layers were washed with brine. The volatile were removed, giving white solids wet with acetic acid. This material was slurried in 1.6 L of EtOAc. Hexane (4L) was added over 1 h. The resulting slurry was cooled to 2 over 1 h and filtered, giving 916 g (87%) of (5R)-3-(4-bromo-3-fluorophenyl)-5-(hydroxymethyl)-1,3-oxazolidin-2-one as coarse white crystals: TLC Rf=0.008 (50% EtOAc/hexane); HPLC rt=2.55 min; mp 114-121 ; [alpha]D=+52.2 c. =1, MeOH); 1H NMR (DMSO) delta7.49 (m, 2H), 7.15 (d,1H, J=8.5 Hz), 5.30 (br s, 1H), 4.54 (m,1H), 3.89 (t, 1H, J=8.6 Hz), 3.67 (m, 1H), 3.50 (dd, 1H, J=3.0, 11.8 Hz), 3.39 (dd, 1H, 3.8, 11.8 Hz); 13C NMR (DMSO) delta158.1 (s, JCF=241 hz), 154.2 (S), 139.7 (S, JCF=10 hz), 133.3 (D), 114.9 (D), 105.9 (d, JCF=29 Hz), 100.9 (s, JCF=21 Hz), 73.3(d), 61.5(t), 45.9 (t); Anal. calc'd for C10H9BrFNO3: C, 41.40; H, 3.13; N, 4.83: Br, 27.55; found: C, 41.11; H, 3.06; N, 4.83: Br, 26.97.

The mixture is electrolyzed at 0.4 V (vs ref. Ag/AgCl) at 15 C until about 9090 coulombs (19 hrs, ca. 94% conversion) of electricity is used. After stirring without electricity for one hour, the anode reaction mixture is transferred to a flask (250 ML) and saturated with NaCl. The reaction mixture is then quenched with 5 g of Na2O3 and extracted with 3 x 50 ML of ethyl acetate. The combined organic solution is washed with 10 ML of 5% H3O4queous solution saturated with NaCl, 15 ML of saturated NaCl solution and dried over 5 g of anhydrous Na2O4 After filtration and removal of solvent under vacuum, (S)-3-chloro-1,2-propanediol is obtained as a pale yellow oil (3.48 g, 66.8% yield based on 94% conversion). The ee of the diol is 54.9% by HPLC analysis of the bis-acetate derivative of the diol on a Chiracell OD column). A sample of this product is analyzed, subsequently, to provide the following physical characteristics: [alpha] [25/D] = +4.43 (c = 2.1, MeOH); literature: EP 0286059 for R-isomer, [alpha] [25/D] = -6.9 (c = 2.0, H2); 1 NMR: (CDCl3 delta 3.6-4.2O); (m, 7H); IR (neat) 3357, 2946, 1432, 1303, 1102, 747 cm-1

A slight vacuum was applied to pull air into the reaction medium, and the reaction was allowed to stir for 1 h. The air inlet was removed, and epichlorohydrin (92.52 g, 78.40 mL, 1.00 mol) was charged after the reaction vessel was purged with nitrogen. The reaction was cooled to 0 C., and water (8.1 g, 8.1 mL, 0.45 mol, 45 mol %) was slowly added, maintaining the reaction temperature below 5 C. The reaction was allowed to stir at room temperature for 16 h. When determined to be complete, the reaction was partitioned between toluene (80 mL) and water (80 mL). The aqueous layer was collected and washed with toluene (80 mL) to remove unreacted epichlorohydrin (isopropyl alcohol (20%) was added to facilitate the phase separation). After concentration of aqueous layer, the residue was vacuum distilled to give (S)-3-chloro-1,2-propanediol (37.4 g, 76% yield, >99% purity, 97% ee; b.p. 115-120 C. a 10 mm Hg).
