摘要

介绍了一种银催化的芳基氧肟酸与炔烃的脱芳基脱羧[3+2]螺烷化反应。该反应提供了在水介质中以中等产率获得一系列氮杂螺[4,5]三烯酮的可靠途径。此外,该反应还具有广泛的底物范围和良好的官能团兼容性。

Silver-Catalyzed Dearomative [3+2] Spiroannulation of Aryl Oxamic Acids with Alkynes

Silver-Catalyzed Dearomative [3+2] Spiroannulation of Aryl Oxamic Acids with Alkynes
A silver-catalyzed dearomative decarboxylative [3+2] spiroannulation of aryl oxamic acids with alkynes is described. The reaction provides reliable access to a range of azaspiro[4,5]trienones in moderate yields in aqueous media. In addition, the reaction exhibits a broad substrate scope and good functional group compatibility.
