Stereoselective Triplet-Sensitised Radical Reactions of Furanone Derivatives
intramolecular reaction, overall, a pyranyl group adds to the α position of the furanone. The effect of conformation was first investigated with compounds 9 a,b carrying an additional substituent on the tether between the furanone and pyranyl moiety. Further information on the effect of conformation and the relativeconfiguration at the pyranyl anomeric centre and the furanone moiety was obtained from
