YieldReaction ConditionsOperation in experiment
With Sulfobalus solfataricus P1 (Sso EST1) In phosphate buffer for 16h;
With methanol; sodium at 23℃; Glass beads; Ultrasonic bath; 4 Example 4; Deracemization of methyl (/?S)-2-(6-methoxynaphthalen-2-yl)propanoate; In a standard 10 mL sample vial were added glass beads (0 2-2.5 mm, Aldrich, 8.7 g), methyl (RS)-2-(6-methoxynaphthalen-2-yl)propanoate (0.7553 g), methyl (S)-2-(6- methoxynaphthalen-2-yl)propanoate (0.0030 g) and NaOMe/MeOH (6.302 g from a stock solution prepared by dissolving 2.2 g Na in 45 mL MeOH). The sample vial was closed with a septum, and placed on an Elma Transsonic T470/H ultrasonic bath. The bath was kept at a constant temperature of 23°C using a cooling spiral that was attached to a Julabo F25 thermostat bath. For sampling, 0.3 mL of the slurry was taken using a syringe, filtered on a P4 glass filter and washed with MeOH (approx. 2 mL). The chiral purity was measured using chiral HPLC. 1H NMR (400 MHz, CDCI3): δ = 7.62 (s, 1 H), 7.57 (d, 1 H, J = 8.5 Hz), 7.48-7.45 (m, 2H), 7.18 (d, 1 H, J = 2.6 Hz), 6.89 (d, 1 H, J = 2.4 Hz), 3.71 (q, 1 H, J = 7.1 Hz), 3.36 (s, 3H), 3.28 (s, 3H), 1.52 (d, 3H, J = 7.1 Hz). HPLC analysis was performed on Chiralcel-OJ (250x4.6 mm ID) column, eluent n-hexane/2- propanol 98/2 v/v%, flow 1 mL.min'1 , room temperature, detection at λ=254 nm. Retention times methyl (S)-2-(6-methoxynaphthalen-2-yl)propanoate 10.5 min, methyl (fi)-2-(6-methoxynaphthalen-2-yl)piOpanoate 1 1.4 min. The results of this experiment are given in Figure 1. It can be seen from this Figure that already an initial enantiomeric excess of 1.5% results in the exponential evolution to an enantiopure methyl (S)-2-(6- methoxynaphthalen-2-yl)propanoate solid phase.

YieldReaction ConditionsOperation in experiment
In acetonitrile; at 80℃; for 24h;Inert atmosphere; Sealed vial; General procedure: Carboxylic acid (0.5 mmol) and MImC (2a, 1.0 mmol) were placed in a dry 20 mL vial with a Teflon tape-coated thread. A magnetic stirbar was added, followed by dry MeCN (1.0 mL), and the vial was quickly sealed with a plastic cap (gas is evolved during the course of the reaction. All experiments should be performed behind a blast shield if a sealed container is used.). The reaction mixture was then stirred at 23 C for 15 min and then heated to 80 C using a heating block for 24 h. The mixture was cooled to room temperature and then the vial was carefully opened (CAUTION: vial under pressure.). The volatiles were removed in vacuo, the resulting residue was dissolved in diethyl ether (20 mL), and then washed with 1 M HCl (10 mL). The aqueous layer was back-extracted with diethyl ether (20 mL) and the organic fractions were combined, washed with a saturated solution of NaHCO3 and then brine, dried over MgSO4, and concentrated in vacuo to afford the desired ester.

With Yarrowia lipolytica Lip2p lipase; In decane; at 20℃; for 100h;Enzymatic reaction;Kinetics; General procedure: In a 2 mL reactor (Eppendorf), 750 lL of culture supernatant (or the concentrate supernatant) containing the enzyme and 750 lL ofracemic ethyl ibuprofen, naproxen or ketoprofen (50 mM indecane) were added. The reactors were stirred in a vortex Genie2 (D. Dutscher, Brumat, France) at room temperature for 100 h.At regular time intervals, the progress of the reaction was monitored by analyzing the organic phase composition after phase separationby centrifugation (dilution 1, 10 and 30 in hexane for the ibuprofen, naproxen and ketoprofen ester, respectively).
