Visible-light-excited 9,10-phenanthrenequinone (PQ*) was used as a photocatalyst for the synthesis of polysubstituted quinolines via the electrocyclization of 2-vinylarylimines. Up to quantitative yields of 2,4-disubstituted quinolines were received after 1 h of excitation with blue LEDs at room temperature when MgCO3 was used as an additive in DCM. On the basis of experimental and DFT studies, we propose that PQ? induces one-electron oxidation of the imine substrate that triggers the electrocyclization mechanism.

A Cu(OAc)2-catalyzed synthesis of 2-arylquinoline N-oxides with easily available arylamines is described. The main features of this reaction are mild reaction conditions, high functional-group tolerance, excellent regioselectivity, and good to excellent yields. This procedure is mild, operationally simple, and constitutes a greener approach to the arylation of quinoline N-oxides.
A Convenient Synthesis of Substituted Quinolines by Thermal Electrocyclic Rearrangement of o-Vinyl Anils under Nonacidic Conditions

, p. 4218 - 4222 (2007/10/02)
Anils 8a-g (Table II) underwent smooth rearrangement and oxidation to the quinolines 9a-g at 155-200 deg C via formation of the 2-3 carbon-carbon bond.These cyclizations proceeded in high yields under nonacidic conditions.It was often possible to prepare
