  Cycloaddition reactions on activated exo-glycals

  摘要：

  Cycloaddition reactions of activated exo-glycals and nitrones proceeded only under microwave activation, with excellent facial selectivities on furanoglycosylidenes and good stereocontrol on the nitrone producing only two diastereomeric spiroisoxazolidines. alpha/beta-Spiro sugar-isoxazolidines are obtained from pyrano exo-glycals. The cycloaddition reaction with nitrile oxide proceeds at room temperature and gives open-chain isoxazoles due to facile beta-elimination of the sugar ring oxygen on the intermediate isoxazoline ring system. All the heterocycles obtained this way can be regarded as nucleoside analogues. (C) 2005 Elsevier Ltd. All rights reserved.

  摘要：

  描述了包含β-氨基酸的1，4-二氮杂2，5-二酮肽的第一合成，其中β碳也是呋喃糖的异头碳。在d- gulo，d- manno，d- allo和d- ribo系列中通过立体选择性控制获得的这些新的异头螺旋糖可被视为新型螺核苷的首批成员。在我们的研究过程中，还分离了包含两个相同的糖β-氨基酸和α-氨基酸残基的两个对称的四聚环肽，这些结构可能作为新的潜在宿主分子而受到关注。

  The first synthesis of 1,4-diazepine 2,5-dione peptides containing a β-amino acid in which the β carbon is also the anomeric carbon of a furanoid sugar is described. These new anomeric spirosugars obtained with a stereoselective control in the d-gulo, d-manno, d-allo and d-ribo series can be regarded as the first members of a new class of spironucleosides. In the course of our study, two symmetrical
