efficient manner by photolysis using quartz equipment.1 We find that use of pyrex filters or ketone sensitisation instead of quartz leads to high yields of the presumed intermediate diastereomeric pair of aziridinoimidazoline dimers, as does brief irradiation in quartz. These dimers have been characterised by spectral and crystallographic methods, and shown to oxidise with DDQ to give imidazoledicarboxylic
