  A Breakthrough for the Photochemical Arylation in the 3-(Phenylmethyl)-2(5H)-furanone system Leading to the Tetrahydroindenofuranone System

  摘要：

  The photochemistry of the 'central methane'-substituted 3-benzyl-2(5H)-furanone system (1) is described. Despite its di-pi-methane structure, photochemical arylation was found to predominate in place of the di-pi-methane rearrangement, and gave substituted tetrahydroindenofuranones (2) in good yields.

  The effect of substitution at the 'central methane' on the photoreactivity of 3-benzylfuran-2(5H)ones 5a-g was investigated. Despite its di-pi-methane structure, photochemical arylation was effected to give substituted indenofuranones 6 in good yields. Only the substitution by phenyl caused the di-pi-methane rearrangement to give a cyclopropanofuranone 18g in moderate yield.
