Microbiological asymmetric reduction of methyl 2-methyl-3-(2-thienyl)-3-oxopropionate (3) by various yeasts was carried out. When Kloeckera saturnus was used, the C3-(S)-alcohols 4c and 4d were obtained, whereas other yeasts such as Lipomyces starkeyi, Saccharomyces fermentati, and Sporobolomyces salmonicolor produced the isomeric C3-(R)-alcohols 4a and 4b. On the other hand, when Endomycopsis fibligera, Hansenula anomala, and Candida albicans were used, the C2-(S)-reduction products 4b and 4c were obtained.
使用多种酵母对 2-甲基-3-(2-噻吩基)-3-氧代丙酸甲酯(3)进行了微生物不对称还原。当使用 Kloeckera saturnus 时,得到了 C3-(S)-醇 4c 和 4d,而其他酵母,如 Lipomyces starkeyi、Saccharomyces fermentati 和 Sporobolomyces salmonicolor 则产生了异构 C3-(R)-醇 4a 和 4b。另一方面,当使用 Endomycopsis fibligera、Hansenula anomala 和 Candida albicans 时,可得到 C2-(S)-还原产物 4b 和 4c。
