Preparation of various heteroaryl propanols 2a–g and of the corresponding propanones 3a–g as starting materials for microbial redox is described. The kinetic resolution of the racemic propanols 2a–g is obtained via oxidation with Pseudomonas paucimobilis and Bacillus stearothermophilus [(R)-alcohols, ee 74–100%]. Similar results are achieved with 3-(2-hydroxypropyl)trifluoromethylbenzene 7 (44%, ee
描述了制备各种杂芳基丙醇2a – g和相应的丙烷3a – g作为微生物氧化还原的起始原料的制备方法。外消旋丙醇2a – g的动力学拆分是通过用假单胞菌和嗜热脂肪芽孢杆菌[(R)-醇,ee 74-100%]氧化获得的。用3-(2-羟丙基)三氟甲基苯7(44%,ee 100%的(R)-醇6)获得了相似的结果。丙烷3a – d和的还原3克含面包酵母和其他真菌的(S)醇(ee 100%)。也可以通过还原1- [3-(三氟甲基)苯基] -2-丙酮7获得纯的(S)醇。1 - [(4,4-二甲基)-2-(Δ 2)唑啉基] -2-丙酮3E和1 [2-(Δ 2)-thiazolinyl)-2-丙酮3F不降低。(S)-5-(2-羟丙基)-3-甲基异唑2d和(S)-2-(2-羟丙基)-4-甲基噻唑2g的杂环被解封为同手性烯胺酮8(78%)和受保护的β-羟基醛9(73%)。将(R)-3-(2-羟丙基)三氟甲基苯6
