of a copper-catalyzed halogen-free protocol to construct indazolo[3,2-b]quinazolinones was developed through sequential inert C–O bond cleavage followed by intramolecular C–N bond formation. This protocol represents an efficient synthetic tool for accessing a more diverse range of functionalized indazolo[3,2-b]quinazolinones. The structure of the newly synthesized indazolo[3,2-b]quinazolinones was unambiguously
通过依次进行惰性C–O键裂解和随后的分子内C–N键形成过程,开发了构建铜吲哚并[3,2- b ]喹唑啉酮的铜催化无卤方案的第一个实例。该协议代表了一种有效的合成工具,可用于获得更多种类的功能化吲唑并[3,2- b ]喹唑啉酮。通过X射线晶体衍射分析明确地确认了新合成的吲唑并[3,2- b ]喹唑啉酮的结构。
