  Electron Transfer-initiated Photocyclization of Substituted a-Dehydro(1-naphthyl)alanines

  摘要：

  On irradiation in the presence of triethylamine, the title compounds (1) having n-butyl and benzyl groups gave preferentially dihydrobenzoquinolinones (2) via electron transfer, whereas the introduction of the bulky tert-butyl and phenyl substituents into 1 resulted in the formation of benzoisoquinoline (3) and 1-azetine (4) derivatives without affording 2.

  Electron transfer-initiated photocyclization of substituted N-acetyl-α-dehydro(1-naphthyl)alanines to 1,2-dihydrobenzo[f]quinolinone derivatives: scope and limitations

  摘要：

  The irradiation of substituted N-acetyl-alpha -dehydro(1-naphthyl)alanines (1) in MeOH containing triethylamine with Pyrex-filtered light gave 1,2-dihydrobenzo[f]quinolinones (2) in preference to benzo[f]isoquinolines (3) and 1-azetines (4). Analysis of substituent effects on the product compositions revealed that the selectivity of 2 has a strong tendency to decrease with increasing steric bulkiness of the alkyl substituent introduced into the starting (Z)-1. From control and fluorescence quenching experiments it was shown that the photocyclization reaction of 1 affording 2 proceeds by an electron-transfer mechanism. The mechanism of this novel cyclization was discussed mainly based on substituent and solvent effects on both the reactivities of the excited singlet-state 1 and the selectivities of the products 2-4.

  It was found that the reaction of the title compounds [(Z)-1] with oxygen in methanol proceeds according to the first-order kinetics to give (Z)-2-imidazolin-5-one derivatives and hydrogen peroxide in quantitative yields. Analysis of substituent and solvent effects on the rate constant for this oxidative cyclization led us to propose that electron transfer from the dialkylamino nitrogen in (Z)-1 to

  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.
