描述了亚甲基苯胺N-氧化物与糖烯酮的1,3-偶极环加成。该加成仅从糖苷配基的相反侧发生,得到相应的烷基α-D-lyxo-己吡喃糖苷-(2,3:5',4')-苯基异恶唑烷丁-4-ulose。这些化合物的氢化容易产生相应的烷基3-脱氧-3-N-苯基氨基甲基-α-D-塔洛吡喃糖苷,其易于转化为乙酸酯。通过1 H NMR研究和使用AM1方法的半经验分子轨道计算,确定了双环化合物的结构和构象。

Enulosides, carbohydrate derivatives containing an alpha,beta-unsaturated carbonyl unit, were designed and obtained in high yields and isomeric purity. All synthesized compounds exhibited antitumoral activity in micromolar range against four tested tumor cells lines, being the best results observed for HL-60 cells. These compounds open new possibilities to prepare an array of more active, site-specific or selective antitumor agents. (C) 2017 Elsevier Masson SAS. All rights reserved.
