The effect of substitution at the 'central methane' on the photoreactivity of 3-benzylfuran-2(5H)-ones 5a-g was investigated.Despite its di-?-methane structure, photochemical arylation was effected to give substituted indenofuranones 6 in good yields.Only
A BREAKTHROUGH FOR THE PHOTOCHEMICAL ARYLATION IN THE 3-(PHENYLMETHYL)-2(5H)-FURANONE SYSTEM LEADING TO THE TETRAHYDROINDENOFURANONE SYSTEM

, p. 1093 - 1096 (2007/10/02)
The photochemistry of the 'central methane'-substituted 3-benzyl-2(5H)-furanone system (1) is described.Despite its di-?-methane structure, photochemical arylation was found to predominate in place of the di-?-methane rearrangement, and gave substituted t
