  1,3-Dipolar cycloaddition between N-benzyl-C-glycosyl nitrones and methyl acrylate en route to glycosyl pyrrolidines

  摘要：

  1,3-Dipolar cycloaddition reactions between three N-benzyl-C-glycosyl nitrones and methyl acrylate afforded key intermediates for the synthesis of glycosyl pyrrolidines. The best result was obtained with a D-galactose derived nitrone which afforded only one isomer in quantitative yield. Absolute configurations were assigned by applying the Kakisawa's rule and X-ray diffraction methods. (C) 2003 Elsevier Ltd. All rights reserved.

  由d-半乳糖和d-葡萄糖立体选择性合成3-糖基-5-甲氧基羰基-异恶唑烷

  摘要：

  据报道，丙烯酸甲酯的区域和立体选择性环加成反应衍生自d-半乳糖和d-葡萄糖的C-糖基硝酮，得到5-甲氧基羰基-3-（戊糖5-基或戊醇-1-基）异恶唑烷。实现了其中之一向4-羟基-2-（五糖基-5-基）吡咯烷衍生物的转化，该衍生物可能在制备多羟基-过氢氮杂azazulenes的途径中有用。

  Regio- and stereoselective cycloaddition of methyl acrylate to C-glycosyl nitrones derived from d-galactose and d-glucose, giving 5-methoxycarbonyl-3-(pentoglycos-5-yl or pentitol-1-yl)isoxazolidines, is reported. Transformation of one of them into a 4-hydroxy-2-(pentoglycos-5-yl)pyrrolidine derivative, potentially useful in a route to polyhydroxy-perhydroazaazulenes, was achieved.

  A short and efficient route to enantiomerically pure hexahydroxy- and pentahydroxy-perhydroazaazulenes, ring-homologues of castanospermine, starting from the sole isoxazolidine derivative obtained in the 1,3-dipolar cycloaddition of a D-galactose-derived nitrone and methyl acrylate, is established. The procedure allows both backbone and stereochemical modulation of the products by choice of the starting monosaccharide. Structural assignment was based on crystallographic analysis of the starting isoxazolidine and NMR techniques. The products were tested for inhibitory activity against several glycosidases.
