AbstractAn iodine-promoted synthesis of acylindolizinecarboxylates via 1,3-dipolar cycloaddition of nitrogen ylides with acetylenecarboxylates and subsequent aromatization for the generation of a wide range of structurally interesting, pharmacologically and photoelectrically significant compounds is reported. Only readily available materials, mild conditions, and operationally trivial reaction protocols
摘要据报道,碘的促进作用是通过氮基与乙炔羧酸的1,3-偶极环加成反应以及随后的芳构化作用来碘化羰基吲哚羧酸酯,以生成各种结构上有意义的,具有药理学和光电意义的化合物。只需要容易获得的材料,温和的条件和操作上琐碎的反应方案。 图形概要
