An efficient method for the synthesis of (E)-1H-inden-1-ones using gold-catalyzed tandem [3,3]-propargyl ester rearrangement followed by Michael addition under mild reaction conditions has been developed. The resulting products are important frameworks found in numerous natural products and pharmaceutically active compounds, as well as being valuable intermediates in organic synthesis.
已开发了一种有效的方法,该方法使用金催化的串联[3,3]-炔丙基酯重排,然后在温和的反应条件下进行迈克尔加成,来合成(E)-1 H -inden-1-one。所得产物是在许多天然产物和药物活性化合物中发现的重要构架,并且是有机合成中的有价值的中间体。
