The guest molecules in the clathrate crystals are converted into the chiral 7-aryl-7-hydroxy-1-azabicyclo[4.2.0]octan-2-one derivatives with high optical yields on exposure to a high pressure Hg lamp. The crystal structures and absolute configurations of the clathrate compound (5a), which consists of (−)-(2R,3R)-2,3-bis(hydroxydiphenylmethyl)-1,4-dioxaspiro[4.5]decane (4) and N-(p-bromophenylcarbonylmethyl)-2-piperidone (1a), and of the chiral product of (−)-(6S,7S)-7-hydroxy-1-azabicyclo[4.2.0]octan-2-one (2a) were determined by X-rays.
