A Cu-catalyzed new sequence involving the Ullmann type intermolecular C–C followed by an intramolecular C–N coupling and then intramolecular aza-Michael type addition (and oxidation) in a single pot afforded various fused N-heterocyclic acetic acid derivatives as inhibitors of PDE4.
一个以铜为催化剂的新序列,涉及乌尔曼类型的分子间C–C偶联,随后是分子内C–N偶联,再然后是在一个反应罐中发生的分子内氮迈克尔类型加成(及氧化),获得了多种作为PDE4抑制剂的融合N-杂环醋酸衍生物。
