Quinoline derivatives
R 0410
Electron Transfer Initiated and Highly Selective Photocyclization of
N-Acyl-α-dehydroarylalaninamides to 3,4-Dihydroquinolinone Derivatives. —
21- 152 Photolysis
of (Z)-N-acyl-α-dehydroarylalaninamides such as (I) and (V) produces the
desired 3,4-dihydro-2-quinolines as the main products. Quinolones of type (III) and/or
dihydrooxazoles of type (IV) are formed in minor amounts.The substituent and amine
base effects reveal that formation of products (II)/(VI) and type (IV) can be explained
by an electron transfer from DBU to the excited-state (E)-(I)/(E)-(V). —
