  摘要：

  酮-和酯-取代的重氮化合物，其含有吡咯烷部分用二铑四乙产生相应的铑卡宾处理。期望它们插入吡咯烷部分的CH键中，但是反应不同。酮-取代铑卡宾体经历了沃尔夫重排。将得到的烯酮继续通过内酰胺和环电环反应-开口，给丙烯酰胺。酯-取代的铑卡宾体进行了[1.2] -的（吡咯烷的移位- 1 -甲基）部分，得到甲基丙烯酸酯。对于每种重排，都建议一种机制。

• Low-generation dendrimers with a calixarene core and based on a chiral <i>C</i>₂-symmetric pyrrolidine as iminosugar mimics

  日期：——

  The preparation of low-generation dendrimers based on a simple calix[4]arene scaffold by insertion of the iminosugar-analogue C₂-symmetric 3,4-dihydroxypyrrolidine is described. This methodology allows a rapid incorporation of a considerable number of iminosugar-like moieties in a reduced volume and in a well-defined geometry. The inclusion of alkali-metal ions (sodium and potassium) in the polar cavity defined by the acetamide moieties at the lower rim of the calixarene was demonstrated, which allows also the rigidification of the dendrimer structure and the iminosugar presentation in the clusters. The combination of the supramolecular properties of calixarenes with the advantage of a dendrimeric presentation of repetitive units opens up the possibility of generating well-defined multivalent and multifaceted systems with more complex and/or biologically relevant iminosugars.

  基于简单的杯[4]芳烃支架制备低代数树状聚合物，通过插入类似亚胺糖的C2对称3,4-二羟基吡咯烷来实现。这种方法允许在较小的体积和明确定义的几何形状中快速引入大量类似亚胺糖的基团。在杯芳烃底部的乙酰胺基团定义的极性腔中展示了碱金属离子（钠和钾）的包容，这也使得树状聚合物结构变得更加刚性，并在团簇中呈现亚胺糖。将杯芳烃的超分子特性与树状聚合物呈现重复单元的优势相结合，为生成具有更复杂和/或生物相关亚胺糖的明确定义多价和多方面系统打开了可能性。

  (3S,4S)-N-Benzyl-3,4-dihydroxypyrrolidine 1 has been used as a building block for new enantiopure macrocyclic polyesters. Two different synthetic approaches are presented leading to complementary results. The structure of the macrocycles synthesized has been confirmed by NMR spectroscopy and FAB mass spectrometry, and that for dimer 8 has been confirmed by X-ray analysis.

• (1S,2S,7R,8aS)- and (1S,2S,7S,8aS)-trihydroxyoctahydroindolizine: Two new glycosidase inhibitors by nitrone cycloaddition strategy
  作者：Andrea Goti、Francesca Cardona、Alberto Brandi、Sylviane Picasso、Pierre Vogel

  日期：1996.6

  The two new epimeric (1S,2S,7R,8aS)- and (1S,2S,7S,8aS)-1,2,7-trihydroxyoctahydroindolizines 4 and 5 have been synthesized via methylenecyclopropane-nitrone cycloaddition-rearrangement methodology employing an enantiomerically pure L-tartaric acid derived nitrone 7b. Highly stereoselective reductions of the intermediate indolizidinone 10b and final deprotection furnished the two title indolizidinetriols 4 and 5, the inhibiting abilities of which toward 24 commercially available glycosidases were tested. Both 4 and 5 are good competitive inhibitors of amyloglucosidases with K-i values of ca. 6 and 75 mu M, respectively. Compared with (+)-lentiginosine 3, 4 and 5 are less powerful inhibitors but, in contrast to 3, the (7R)-hydroxy analogue 4 possesses a weak inhibiting activity toward alpha-L-fucosidase from bovine epididymis. A model to rationalize the structure-activity relationship of (+)-lentiginosine and the two new 7-hydroxylentiginosines toward glucoamylases is proposed on the basis of their structural comparison with known inhibitors and with the natural enzyme's substrate amylose.
