A PtCl4-catalyzed hydroamination-triggered cyclization strategy to access biologically interesting N-containing heterocycles such as pyrrolo[1,2-a]quinoxalines, indolo[1,2-a]quinoxalines, and indolo[3,2-c]quinolines is described. The reaction makes use of aminoaromatics such as 1-(2-aminophenyl)pyrroles, N-(2-aminophenyl)indoles, 2-(2-aminophenyl)indoles, and alkynes having a tethered hydroxyl group
一种PtCl 4催化的加氢胺触发的环化策略,以获取生物学上有趣的含N杂环,如吡咯并[1,2- a ]喹喔啉,吲哚[1,2- a ]喹喔啉和吲哚[3,2- c ]喹啉描述。该反应利用氨基芳族化合物,例如1-(2-氨基苯基)吲哚,N-(2-氨基苯基)吲哚,2-(2-氨基苯基)吲哚和具有束缚羟基的炔烃。从机理上讲,该反应非常吸引人,因为它涉及由单一金属催化剂PtCl 4催化的多个催化循环。当反应在微波辅助条件下进行时,我们观察到了速率的显着提高。

One of the best ways to access collections of small molecules is to use various techniques in diversity‐oriented synthesis (DOS). Recently, a new form of DOS, namely “relaycatalyticbranchingcascades” (RCBCs), has been introduced, wherein a common type of starting material reacts with several scaffold‐building agents (SBAs) to obtain structurally diversemolecularscaffolds under the influence of
