stereoselective, three-component method has been developed to synthesize pyrrolidine and pyrrolizidine containing spirooxindole derivatives. The interaction between the dipolarophile α,β-unsaturated carbonyl compounds and the dipole azomethine ylide formed in situ by the reaction of 1,2-dicarbonyl compounds and secondary amino acids is referred to as the 1,3-dipolar cycloaddition reaction. The reaction
已经开发了一种高度立体选择性的三组分方法来合成含有螺氧吲哚衍生物的吡咯烷和吡咯里西啶。亲偶极α,β-不饱和羰基化合物与1,2-二羰基化合物与仲氨基酸反应原位形成的偶极甲亚胺叶立德之间的相互作用称为1,3-偶极环加成反应。优化反应条件以实现优异的立体选择性和区域选择性。更短的反应时间、简单的后处理和优异的产率是本方法的显着特征。化合物6i的一个例子的各种光谱方法和单晶 X 射线衍射检查验证了预期产物的立体化学。针对α-葡萄糖苷酶和α-淀粉酶测试了新合成的螺氧吲哚衍生物的抗糖尿病活性。发现化合物6i对 α-葡糖苷酶和 α-淀粉酶具有有效的抑制活性,分子对接研究进一步证明了这一点。
