  Chemoenzymatic Synthesis of Isogalactofagomine

  摘要：

  A new chemoenzymatic synthesis of optically pure isogalactofagomine 2 starting from achiral starting materials is presented. Dimethyl 4-hydroxypyridine-3,5-dicarboxylate (7) was synthesized and converted to the corresponding saturated piperidine 8. Then the key step of the synthesis was carried out: Lipase M catalyzed hydrolysis of the prochiral diester 8 to cause formation of an asymmetric monoacid with at least 98% enantiomeric excess. Reduction of the acid, saponification of the remaining ester, and radical iododecarboxylation gave an iodide that after substitution with silver trifluoroacetate and hydrolysis gave 2.

  group in the 4-position relative to the amine were 0.4 pH units more acidic than the corresponding compound with an axial OH. A similar effect was observed for the COOMe substituent. The difference in electron-withdrawing power of axial and equatorial substituents was explained by a difference in charge-dipole interactions in the two systems. Since this stereoelectronic substituent effect causes differences

  从大量的羟基化哌啶和六氢哒嗪的共轭酸的pK（a）值，发现在具有轴向或赤道羟基（OH）基团（相对于胺而言）的立体异构体之间，碱度存在一致的差异。与其他相同的具有轴向OH基团的化合物相比，在3位具有赤道OH基团的化合物的酸度高0.8个pH单位，而相对于胺在4位具有赤道OH基团的化合物的酸度比其他的酸碱度高0.4个pH单位。带有轴向OH的相应化合物。对于COOMe取代基观察到类似的效果。轴向和赤道取代基的吸电子能力的差异是由两个系统中电荷-偶极相互作用的差异解释的。由于这种立体电子取代基效应导致不同构象异构体的碱性不同，因此发现某些哌啶和六氢哒嗪在质子化时会改变构象。描述了一种预测立体异构体的哌啶的pK（a）的方法。

  A series of hydroxylated piperidine oligomers that resemble oligosaccharides is synthesised. Prepared were 5, a mimic of 3-O-L-fucopyranosyl-D-galactopyranose, 6, a mimic of 3-O-D-galactopyranosyl-D-galactopyranose and 7, a mimic of 3-O-3-O-[3-O-(L-fucopyranosyl)-D-galactopyranosyl]-D-galactopyranosyl}-D-galactopyranose. Conformational analysis of the new compounds using NMR spectroscopy showed them to have predominant conformations that were similar to those adopted by β-O-glycosides. The inhibition of a series of glycosidases by 5–7 was investigated and found to be inferior to that of the corresponding unsubstituted isofagomines.
