Regio - and stereoselective photocycloadditions of heterocyclic 2,3- diones - Evidence for an unexpected 1,2-aroyl migration

Photocyclization of the heterocyclic 2,3-diones 1a-d with electron rich alkenes affords regio- and stereoselectively the 2+2 adducts 2, from 1b with benzophenone as photosensitizer also the Paterno-Buchi adduct 3 is obtained. Similarly, with phenylethyne

17O-labeling studies on the reaction of 4-benzoyl-5- phenylfuran-2,3-dione with carbodiimides [1,2]

The reactions of 4-benzoyl-5-phenyl-furan-2,3-dione 1 with isopropyl-phenylcarbodiimide as well as dimethylcarbodiimide are investigated with aid of 17O-labeling experiments. From comparing the distribution of the label within starting material
