  Synthesis of Enantiopure Fluorohydrins Using Alcohol Dehydrogenases at High Substrate Concentrations

  摘要：

  The use of purified and overexpressed alcohol dehydrogenases to synthesize enantiopure fluorinated alcohols is shown. When the bioreductions were performed with ADH-A from Rhodococcus ruber overexpressed in E. coli, no external cofactor was necessary to obtain the enantiopure (R)-derivatives. Employing Lactobacillus brevis ADH, it was possible to achieve the synthesis of enantiopure (S)-fluorohydrins at a 0.5 M substrate concentration. Furthermore, due to the activated character of these substrates, a huge excess of the hydrogen donor was not necessary.

  Fluoro-substituted aliphatic nitriles are shown to undergo the Houben–Hoesch reactions with arenes in CF3SO3H to give fluoro-substituted ketones in good yields. The fluorine substituents appear to enhance the reactivities of the nitriles (and the nitrilium ion intermediates) compared to similar aliphatic nitriles. Fluoro-substituted ketones are also shown to be accessible through the reactions of organometallic

  氟取代的脂肪腈显示出在 CF 3 SO 3 H 中与芳烃发生 Houben-Hoesch 反应，以良好的产率得到氟取代的酮。与类似的脂肪族腈相比，氟取代基似乎增强了腈（和腈离子中间体）的反应性。氟取代的酮也可以通过有机金属试剂和氟取代的腈的反应获得。

  The external quenching method based on flow microreactors allows the generation and use of short‐lived fluoro‐substituted methyllithium reagents, such as fluoromethyllithium, fluoroiodomethyllithium, and fluoroiodostannylmethyllithium. Highly chemoselective reactions have been developed, opening new opportunities in the synthesis of fluorinated molecules using fluorinated organometallics.
