  Lipase catalyzed enantioselective desymmetrization of a prochiral pentane-1,3,5-triol derivative

  摘要：

  The enantioselective desymmetrization of the prochiral 3-O-silyl protected pentanetriol derivative 3 was carefully investigated. At -10 degrees C, the bacterial lipase from Burkholderia cepacia immobilized on ceramic particles led to monoacetate (S)-4 in 52% yield and > 99.9% ee. At a reaction temperature of -40 degrees C the yield and enantioselectivity were even higher, but the reaction time was very long. Theoretical simulations of the reaction progress indicated an enantioselectivity of 25:1 at -10 degrees C and 35:1 at -40 C. (S)-4 was converted into the enantiomerically pure building block 5-azidopentane-1,3-diol (S)-7 in two steps. The absolute configuration of (S)-7 was determined by exciton-coupled circular dichroism (ECCD) of diester (S)-8. (c) 2006 Elsevier Ltd. All rights reserved.

  We synthesized and investigated the NMDA and σ1 receptor affinity of enantiomerically pure 2-(2-phenyl-1,3-dioxan-4-yl)ethanamines 17–26. The primary amines (R,R)-18–20 with an axially oriented phenyl moiety in position 2 interacted with high enantioselectivity (eudismic ratios 70–130) and high affinity (Ki((R,R)-19) = 13 nM) with the PCP binding site of the NMDA receptor.

• Conversion of a pentane-1,3,5-triol derivative using lipases as chiral catalysts and possible function of the lid for the regulation of substrate selectivity and enantioselectivity
  作者：Jens Köhler、Bernhard Wünsch

  DOI：10.3109/10242422.2012.661726

  日期：2012.3

  The enantioselective desymmetrization of a prochiral 3-O-silyl protected pentane-1,3,5-triol derivative was achieved by lipase-catalysed hydrolysis. The lipase from B. cepacia led to 95.4% enantiomeric excess (ee) of the (R)-configured compound (R)-4 at a theoretical yield of 79% and was isolated with 98.2% ee and 27% yield. Furthermore, it was found that the ee switched from an excess of (R)-4 to an excess of (S)-4 during the course of the reaction using crude lipase from C. rugosa under the same conditions. This finding was investigated in detail and compared to the change of substrate selectivity known for the lipase from M. miehei. It is supposed that both phenomena may result from a movement of the lid.
