[摘要]：Irradiation of the title compound having an N'-methyl group in 2-propanol and dichloromethane containing (S)-1-methyl-2-pyrrolidinemethanol at room temperature afforded (R)-3,4-dihydrobenzo[f]quinolinone derivative in enantiomeric excesses (ee's) of 7 and 30%, respectively. On the other hand, the corresponding (S)-enantiomer was obtained in 21-23% ee's on room temperature irradiation in the above solvents containing (S)-nicotine which enhanced these ee values up to 34-59% at 78 degrees C. |
