  由D-糖类合成二羟基和三羟基脯氨酸衍生物：在合成多取代的吡咯烷并生物活性的1C-芳基/烷基吡咯烷中的应用

  摘要：

  从D-糖和2C-甲酰基-糖合成了六种不同类型的O-苄基保护的脯氨酸衍生物。一种二-O-苄基保护的脯氨酸衍生物已被用于通过立体选择性方式通过[3 + 2]环加成反应合成多取代的吡咯并核苷。此外，我们还报告了通过多种D的双重还原胺化反应，对具有生物活性的1C-芳基/烷基吡咯烷（即4-上消旋胺B，4-上消旋胺A，1C丁基和1C-甲基吡咯烷）进行立体选择性合成的报道。 -葡萄糖衍生的二酮与对甲氧基苄胺。

  A diversity-oriented synthesis is described for functionalized chiral building blocks (i.e., 7, 9, 10, 16, and 17) and the biologically active iminosugar, fucosidase inhibitor (2S,3R,4R,5R)-2-(hydroxymethyl)-5-methylpyrrolidine-3,4-diol (22), starting from common chiral intermediate 1a which is obtained through a regioselective reductive cleavage of a bis(benzylidene) acetal.

  A series of naturally occurring pyrrolidine alkaloids and analogues, with the general structure of trideoxy-2,5-iminohexitols (imino- or azasugars), have been enantiosynthesized using triorthogonally protected pyrrolidines, previously prepared from commercial d-fructose, as homochiral starting materials. The inhibitory activity of some of the described compounds against glycosidases and glycosyltransferases makes them potential therapeutic agents.

• Use of dihydroxyacetone phosphate-dependent aldolases in the synthesis of deoxy aza sugars

  The use of fructose-1,6-diphosphate (FDP), fuculose-1-phosphate (Fuc-1-P) and rhamnulose-1-phosphate (Rham-1-P) aldolases in organic synthesis is described. Fuc-1-P, Rham-1-P, and their phosphate-free species have been prepared and characterized. Both Fuc-1-P and Rham-1-P aldolases accept 3-azido-2-hydroxypropanal as a substrate to form L-omega-azidoketose phosphates, which upon dephosphorylation and hydrogenolysis on Pd/C, gave 1-deoxyazasugars structurally related to D-galactose and L-mannose. Hydrogenolysis of the enzyme products azidoketose 1-phosphates, however, gave 1,6-dideoxyazasugars structurally related to 6-deoxygalactose and L-rhamnose. Explanations for the stereoselectivity in the hydrogenolysis reactions were provided. Similarly, FDP aldolase catalyzed the aldol condensation reaction with 2-azido-3-hydroxypropanal to afford a new synthesis of 2(R),5(S)-bis(hydroxymethyl)-3(R),4(R)-dihydroxypyrrolidine, a potent inhibitor of a number of glycosidases. A new empirical formula is developed to relate the inhibition constants and inhibitor binding for alpha- and beta-glucosidases.
