2-Aminobenzyl alcohol is oxidatively cyclised with an array of ketones in dioxane at 80 °C in the presence of a catalytic amount of a ruthenium catalyst and KOH to afford the corresponding quinolines in high yields.

2-Aminobenzyl alcohol reacts with an array of ketones in toluene/poly(ethylene glycol) (PEG-2000) at 100 °C in the presence of a palladium catalyst along with KOH under an atmosphere of air to give the corresponding quinolines in good yields. The catalytic system could be recovered and reused five times without any loss of catalytic activity.

2-Aminobenzylalcohol reacts with an array of ketones in dioxane at 100 °C in the presence of a catalytic amount of CuCl2 along with KOH under O2 atmosphere to afford the corresponding quinolines in good yields. 2-Aminobenzylalcohol is also oxidatively coupled and cyclized with various aldehydes by step-by-step procedure, an initial treatment of 2-aminobenzylalcohol in the presence of CuCl2 and KOH

A highly effective one-pot Friedländer quinoline synthesis using inexpensive reagents has been developed. o-Nitroarylcarbaldehydes were reduced to o-aminoarylcarbaldehydes with iron in the presence of catalytic HCl (aq.) and subsequently condensed in situ with aldehydes or ketones to form mono- or di-substituted quinolines in high yields (66–100%).

Quinolines are prepared in an oxidative cyclizationreaction between 2-aminobenzylalcohol and ketones. This reaction, that involves a hydrogen transfer, is mediated solely by a base without the need for a transition metal catalyst.
