The phenyl glycidyl ether derivatives have been kinetically resolved with the growing cells of Bacillus alcalophilus MTCC10234 yielding (S)-epoxides with up to >99% ee and (R)-diols with up to 89% ee. The enantiomeric ratio (E) of up to 67 has been obtained for biohydrolysis process. The effect of different substituents of phenyl glycidyl ether on the biocatalytic efficiency of B. alcalophilus MTCC10234
苯缩水甘油醚衍生物已经与嗜碱芽孢杆菌MTCC10234的生长细胞动力学分离,产生了(S)-环氧化合物,其ee含量高达> 99%,(R)-二醇的ee含量高达89%。对于生物水解过程,已获得高达67的对映体比率(E)。苯基缩水甘油基醚的不同取代基对嗜酸芽孢杆菌MTCC10234的生物催化效率的影响表明,甲基和氯取代的芳基缩水甘油基醚衍生物较为可取,而硝基衍生物的转化速度较慢。将含有在两个邻位均具有甲基的大体积芳基的2,6-二甲基苯基缩水甘油醚用N-甲基-N-二甲基苯甲酸酯进行拆分。E = 39。
