  Copper(I)-Catalyzed Intramolecular O-Arylation for the Synthesis of 2,3,4,9-Tetrahydro-1H-xanthen-1-ones with Low Loads of CuCl

  摘要：

  As little as 0.5 mol % CuCl is sufficient to catalyze the intramolecular O-arylation of easily accessible 2-(2-bromobenzyl)cyclohexane-1,3-diones to provide the corresponding 2,3,4,9-tetrahydro-1H-xanthen-1-ones with yields ranging from 83% to 99%.

  A simple, environmentally friendly, tandem C-benzylation and intramolecular O-arylation for the sequential one-pot synthesis of functionalised 4H-chromenes is reported. The reactions between 2-halobenzylbromides and cyclic-1,3-diketones were catalysed by CuO/oxalohydrazide/hexane-2,5-dione in water to produce 2,3,4,9-tetrahydro-1H-xanthen-1-ones in moderate to high yields.A simple, environmental friendly, tandem C-benzylation and intramolecular O-arylation for the sequential one-pot synthesis of 2,3,4,9-tetrahydro-1H-xanthen-1-ones in water is described.
