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。
