5- Benzoyloxy-2 -furanone, reaction with aryl nitrile oxides

It was found that the reaction of 5-acetoxy- and 5-benzoyloxy-2(5//)-furanones 174 with aryl nitrile oxides afforded only one cycloadduct, the condensed isox-azoline 233 (88TL5317). In principle, there are four possible cycloadducts 233 and 234 resulting from the anti approach of the 1,3-dipolarophile to the acetoxy group (with exo configuration of the acetoxy substituent), and two further isomers...
