Azetidine-2,4,-diones via photocyclisation of bis (phenyolglyoxylolyl)-alkylamines. A novel photochemical reaction involving a 1,5-benzoyl shift
Abstract
Irradiation of bis(phenylglyoxyloyl)alkylamunes leads to cyclisation involving a 1,5-benzoyl shift and the formation of the corresponding 1-alkyl-3-benzoyloxy-3 phenylazetidine-2,4-diones.
