The rhodium(III)-catalyzed coupling of azomethineylides with alkynes via CH activation has been developed for the synthesis of indenamines in moderate to high yields. The coupled products can be further oxidized to indenones and derivatives.

A facile I2O5-mediated 1,5-cyclization of aryldiynes with H2O has been successfully developed, leading to a broad range of substituted 3-acyl-1-indenones in moderate to excellent yields. The protocol has advantages of a metal-free process, mild reaction conditions, simple operation, and broad functional group tolerance. In the reaction, H2O is used as both a cosolvent and an oxygen source.
已经成功地开发了一种容易的I 2 O 5介导的芳基二炔与H 2 O的1,5-环化反应,从而以中等到极好的收率产生了广泛的取代的3-酰基-1-茚满酮。该方案具有无金属工艺,温和的反应条件,简单的操作和广泛的官能团耐受性的优点。在反应中,H 2 O既用作助溶剂又用作氧气源。
