experimental part, p. 199 - 206 (2010/05/18)
An investigation was undertaken to elucidate substituent effects on the photoreactivity of 1,2,4-triazole-substituted α-dehydroarylalaninamides [(Z)-1] as well as on the selectivity of 2(1H)-quinolinone derivatives (2) from a synthetic point of view. It was found that photoinduced electron transfer-initiated cyclization of (Z)-1 bearing a meta-substituted phenyl or a 4-substituted naphthalen-1-yl group in methanol proceeds with a moderate to good efficiency affording the corresponding product 2 in a selectivity ranging from 33 to 100%.

scheme or table, p. 739 - 746 (2010/09/18)
The irradiation of the title compounds [(Z)-1] in nitrogen-saturated methanol containing triethylamine (TEA) at room temperature was found to quantitatively afford 2(1H)-benzo[f]quinolinone (2) and 3,4-dihydro-3-(3-methyl- 5-substituted 1,2,4-triazol-4-yl
