  名称：

  An allylic azide route to 4'-azido carbocyclic nucleosides. Synthesis of (.+-.)-(1'.alpha.,2'.alpha.,3'.beta.)- and (.+-.)-(1'.alpha.,2'.beta.,3'.beta.)-1-[1-azido-2-hydroxy-1-(hydroxymethyl)-3-cyclopentyl]thymine

  摘要：

  Treatment of (+/-)-1-[[(tert-butyldiphenylsilyl)oxy]methyl]-3-methoxycyclopent-1-ene (17) with azidotrimethylsilane under Lewis acid catalyzed conditions gave an equilibrium mixture of allylic azides 18 and 19. Epoxidation of this mixture with peroxybenzimidic acid gave key epoxide (+/-)-(1alpha,2alpha,5alpha)-2-azido-2-[[tert-butyldiphenylsilyl)oxy]methyl]-6-oxabicyclo[3.1.0]hexane (5). Alternate routes designed to give tertiary azide precursors to 5 led to unanticipated products which are described. Title compound 28 was prepared by ring opening of 5 under Vorbruggen conditions followed by deprotection. Inversion of configuration at C-6' to give compound 30 was effected via O2,6'-cyclic intermediates 31 and 32. The relative stereochemistry of compounds in this series was suggested by NOE data for bromohydrins 23 and 26 and was confirmed by preparation of the fused oxetane 34.

  Hindered amines substituted on the N-atom with an —O—E—OH moiety are particularly effective in stabilizing polyolefin and automotive coating compositions against the deleterious effects of oxidative, thermal and actinic radiation where the presence of the OH group on the compounds adds important properties not attainable by the use of normal —O—E moieties.

  在氮原子上取代带有—O—E—OH官能团的阻碍胺，特别有效地稳定聚烯烃和汽车涂料组合物，以抵御氧化、热和光辐射的有害影响，其中化合物上OH基团的存在增加了重要的性能，这是通过使用普通的—O—E官能团无法获得的。
