Highly enantioselective photocyclization of N-(aryloylmethyl)-.delta.-valerolactams
摘要:
Photoirradiation of powdered inclusion compounds of N-(aryloylmethyl)-delta-valerolactams with optically active host compound in a water suspension gave 7-aryl-7-hydroxy-1-azabicyclo[4.2.0]octan-2-one derivatives of high optical purities.
