The irradiation of (Z)-N-acyl-α-dehydroarylalaninamides [(Z)-1] in methanol containing 1,8-diazabicyclo[5.4.0]undec-7-ene gave substituted 3,4-dihydro-2-quinolinones (2) in high yields along with minor amounts of 2-quinolinone (3) and 4,5-dihydrooxazole (

Photochemical cyclizations of (Z)-N-(substituted phenylacetyl)-α-dehydro(3,4-dimethoxyphenyl)alaninamides in methanol were found to proceed regioselectively giving papaverine analogs in satisfactory yields, irrespective of the substituent introduced. MM2
A new route to papaverine analogs via photocyclization of substituted N-acyl-α-dehydrophenylalaninamides

, p. 1779 - 1786 (2007/10/03)
(Z)-N-Phenylacetyl-α-dehydro(3,4-dimethoxyphenyl)alaninamide derivatives [(Z)-1] were prepared in satisfactory yields, starting from 3,4-dimethoxybenzaldehyde. On irradiation in methanol, regioselective photocyclization of these derivatives proceeded to g
