Phosphine-catalyzed Domino reactions1 with allenoates have emerged as a key tactics for the generation of molecular complexity.
Iridoids represent a large and still expanding group of cyclopentan[c]pyran monoterpenoids.
四唑作为富氮杂环化合物,在制药1、含能材料2、多孔材料3 以及燃料4 等方面具有广泛的研究及使用价值.然而,由于四唑二取代化合物具有1,5-二取代和2,5-二取代两种取代类型,在制备四唑高分子及其他四唑衍生物的过程中,常常会因四唑取代类型的不同而生成多种产物,为其分离纯化带来了很大的不便.
Our study focused on building C-S,and S-S bonds by using inorganic sulfide agents such as Na2S2O31and RSO2Na.
含氮杂环广泛存在于天然产物,药物,材料分子中,因而,它们的合成方法一直备受化学家们的关注[1].近年来,随着过渡金属催化的C-H 键活化反应的快速发展,通过对分子内的C-H 键直接胺化或酰胺化反应来构建C-N 键正逐渐成为更加有效的含氮杂环的合成策略.
The spirooxindoles are among the most privileged scaffolds in medicinal chemistry.
