  Hypervalent Iodine(III)-Induced Intramolecular Cyclization of α-(Aryl)alkyl-β-dicarbonyl Compounds:  A Convenient Synthesis of Benzannulated and Spirobenzannulated Compounds

  摘要：

  A novel hypervalent iodine(III)-induced direct intramolecular cyclization of alpha-(aryl)alkyl-beta -dicarbonyl compounds has been described. Both meta-and para-substituted phenol ether derivatives containing acyclic or cyclic 1,3-dicarbonyl moieties at the side chain undergo this reaction in a facile manner. The reactions afford benzannulated and spirobenzannulated compounds that are of biological importance. The reaction is found to be general, mild,: and high yielding. The mechanism: of the reaction has been shown to involve a cation radical intermediate.
