  Total syntheses of hyacinthacine A2 and 7-deoxycasuarine by cycloaddition to a carbohydrate derived nitrone

  摘要：

  Practical syntheses of nitrone 8 by two different approaches from sugars are reported. Its use as a versatile intermediate in highly selective 1,3-dipolar cycloaddition reactions constitutes the key step for novel total syntheses of hyacinthacine A(2) (3) and 7-deoxycasuarine (20) by simple transformations of a common isoxazolidine adduct.

• Synthesis, Biological Evaluation and Docking Studies of Casuarine Analogues: Effects of Structural Modifications at Ring B on Inhibitory Activity Towards Glucoamylase

  We report the total synthesis of a series of pyrrolizidine analogues of casuarine (1) and their 6-O-alpha-glucoside derivatives. The synthetic strategy is based on a totally regio- and stereoselective 1,3-dipolar cycloaddition of suitably substituted alkenes and a carbohydrate-based nitrone. We also report the evaluation of the biological activity of casuarine and its derivatives towards a wide range

  我们报告了木麻黄 (1) 及其 6-O-α-葡萄糖苷衍生物的一系列吡咯里西啶类似物的全合成。合成策略基于适当取代的烯烃和基于碳水化合物的硝酮的完全区域和立体选择性 1,3-偶极环加成。我们还报告了对木麻黄及其衍生物对多种糖苷酶的生物活性的评估，以及一项专注于葡糖淀粉酶 (GA) 的分子建模研究，其中研究了酶腔内新合成化合物的结合模式。结果突出了木麻黄及其衍生物的突出结构特征，使其成为选择性葡糖淀粉酶抑制剂。
