An I2–DMSO promoted domino protocol was developed for the synthesis of 1,2,2-triarylethanones from readily available aromatic methyl ketones and methoxybenzenes. The 1,2,2-triarylethanones are important precursors for the synthesis of Tamoxifen and Droloxifene. The use of mild reaction conditions, high yield, and single step synthesis are the advantages of the present protocol.
开发了由I 2 -DMSO促进的多米诺协议,用于从容易获得的芳族甲基酮和甲氧基苯合成1,2,2-三芳基酮。1,2,2-三芳基酮是合成他莫昔芬和屈洛昔芬的重要前体。使用温和的反应条件,高收率和一步合成是本方案的优点。
