  The Stereochemical inversion of (R)-5-hydroxymethyl-3-tert-butyl-2-oxazolidinone (1a) or (R)-5-hydroxymethyl-3-isopropyl-2-oxazohdinone (1b) to the corresponding (S)-isomer was accomplished via a key intermediate, (R)-3-N-ethoxycarbonyl-N-tert-butylamino-1, 2-epoxypropane (5a) or (R)-3-N-ethoxycarbonyl-N-isopropylamino-1, 2-epoxypropane (5b), in a high enantiomeric excess. (S)-1a (99% e.e.) or (S)-1b (97% e.e.) was thus obtained from the respective (R)-isomer (1a; 99% e.e., 1b; 95% e.e.).

  The enzymatic hydrolysis of (R, S)-5-acyloxymethyl-3-alkyl-oxazolidin-2-one I and the behavior of (S)-I for extraction with an organic solvent were examined so as to extend the biological resolution to racemates, and to learn about more appropriate combinations of substrates with lipases on the asymmetric hydrolysis. The combination of (R, S)-5-hexanoyloxymethyl-3-tert-butyl-oxazolidin-2-one 4 with lipoprotein lipase Amano 3 (L. P. L. Amano 3, origin; Pseudomonas aeruginosa) and that of (R, S)-5-octanoyloxymethyl-3-isopropyl-oxazolidin-2-one 14 with L. P. L. Amano 3 efficiently gave (S)-5-hydroxymethyl-3-tert-butyl-oxazolidin-2-one (S)-lla (99% e.e.) and (S)-5-hydroxymethyl-3-isopropyl-oxazolidin-2-one (S)-IIb (99% e.e.),respectively. (S)-IIa and (S)-IIb could be considered to be favorable intermediates for preparing optically active β-blockers.

  Hydrophobic (R, S)-5-acyloxymethyl-3-alkyl-2-oxazolidinones were successfully hydrolyzed stereospecifically with lipoprotein lipase Amano 3 (LPL) adsorbed on Amberlite XAD-7. The LPL immobilized on the resin was not desorbed on washing with phosphate buffer, toluene or hexane. The activity loss of the column was little during storage for five months at room temperature. Stereospecific hydrolyses were performed pulsewise with the column, and separation of the hydrophobic (S)-ester from the hydrophilic (R)-alcohol was also performed on the same column utilizing the hydrophobic interaction between the (S)-ester and the support resin. The immobilized LPL column was stable on repetition of these operations for over 20 times. The optical purities of the obtained (S)-oxazolidinones, which were favorable intermediates for the synthesis of (S)-β-blockers, were 96-98% e.e.

  用吸附在 Amberlite XAD-7 上的脂蛋白脂肪酶天野 3（LPL）成功地立体定向水解了疏水性（R，S）-5-乙酰氧基甲基-3-烷基-2-恶唑烷酮。用磷酸盐缓冲液、甲苯或正己烷洗涤时，固定在树脂上的 LPL 不会解吸。在室温下储存五个月后，色谱柱的活性损失很小。利用该色谱柱进行了立体特异性水解，并在同一色谱柱上利用(S)-酯和支撑树脂之间的疏水作用分离了疏水的(S)-酯和亲水的(R)-醇。固定化 LPL 色谱柱在重复上述操作 20 多次后保持稳定。获得的(S)-噁唑烷酮是合成(S)-β-受体阻滞剂的有利中间体，其光学纯度为 96-98%。
