  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.

• A bioisosteric oligosaccharide mimetic based on isofagomine-type monomers

  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.

  合成了一系列类似于寡糖的羟基化哌啶低聚物。制备了5个，3-O-L-吡喃岩藻糖基-D-吡喃半乳糖的模拟物，6个，3-O-D-吡喃半乳糖基-D-吡喃半乳糖的模拟物和7个，3-O-D-吡喃半乳糖基-D-吡喃半乳糖的模拟物3-O-3-O-[3-O-(L-吡喃岩藻糖基)-D-吡喃半乳糖基]-D-吡喃半乳糖基}-D-吡喃半乳糖。使用核磁共振波谱对新化合物进行构象分析表明，它们具有与 β-O-糖苷相似的主要构象。对 5-7 一系列糖苷酶的抑制作用进行了研究，发现其效果不如相应的未取代的异法戈明。
