Lipase-catalyzed transesterifications and biological reductions were used to obtain the (S)-enantiomers of 3-chloro-1-(1,3-dithian-2-yl)-2-propanol and 1-(1,3-dithian-2-yl)-3-fluoro-2-propanol and their (R)-acetates. (S)-3-Chloro-1-(1,3-dithian-2-yl)-2-propanol and (R)-3-chloro-1-(1,3-dithian-2-yl)-2-propyl acetate were converted into the respective enantiomers of 2-(1,3-dithian-2-ylmethyl)oxirane
脂肪酶催化的酯交换和生物还原被用于获得 3-chloro-1-(1,3-dithian-2-yl)-2-propanol 和 1-(1,3-dithian-2) 的 (S)-对映异构体-基)-3-氟-2-丙醇和它们的(R)-乙酸酯。(S)-3-Chloro-1-(1,3-dithian-2-yl)-2-propanol 和 (R)-3-chloro-1-(1,3-dithian-2-yl)-2-乙酸丙酯被转化为2-(1,3-二噻烷-2-基甲基)环氧乙烷的相应对映异构体。在这项工作中,我们还分离了一种新的 gem-di 取代环氧化物,2-(氯甲基)-2-(1,3-二噻烷-2-基)环氧乙烷。(© Wiley-VCH Verlag GmbH & Co.
