Synthesis of 2(5H)-Furanone Derivatives with Biphenyl Ether Unit

Abstract: Sixteen 5-(4'-alkoxybiphenyl-4-yloxy)-3,4-dihalo-2(5H)-furanones are synthesized via the direct dehydrative etherification reactions of 4'-alkoxybiphenyl-4-ol with mucochloric acid and mucobromic acid, respectively, using sulfuric acid as catalyst at reflux in toluene from 30% to 58% yields (mostly over 47%). The moderate yields may be due to that this acid-catalyzed etherification should be a S N 2 nucleophilic substitution reaction. The structures of all newly synthesized compounds are elucidated and confirm… Show more
