of heterocyclic product space accessible by the Castagnoli–Cushman reaction (CCR) has been achieved via the use of glutaric anhydride analogues containing endocyclic substitutions with oxygen, nitrogen, and sulfur. Incorporation of these heteroatoms in the anhydride’s backbone results in enhanced reactivity and generally lower temperatures that are required for the reactions to go to completion. These
通过使用含有氧,氮和硫的内环取代的戊二酸酐类似物,已经实现了Castagnoli-Cushman反应(CCR)可访问的杂环产物空间的显着扩展。将这些杂原子掺入酸酐的主链中可提高反应活性,并通常降低反应完成所需的温度。鉴于最近被认为是铅导向合成的有效工具的CCR,这些发现尤其重要。
