Para substituted benzaldehydes as expedient reagents for the oxidative aromatization of hydroquinoline

A Cannizzaro-type reaction of tetrahydro-5(1H)-quinolinones with para substituted benzaldehydes in the presence of a base formed the corresponding quinoline and aryl methanol rather than arylidene derivatives because of the oxidation of tetrahydroquinoline and reduction of benzaldehydes as a result of unprecedented hydride transfer from tetrahydroquinoline to arylaldehydes. The reaction proceeds best with the participation of substituents with +M effect in substrate molecule.

HETEROCYCLIZATION OF TRIKETONES OF THE 2-(3-OXOPROPYL)CYCLOHEXANE-1,3-DIONE SERIES

Triketones of the 2-(3-oxopropyl)cyclohexane-1,3-dione series have been shown for the first time to react with boron trifluoride etherate to give the novel 5-oxo-5,6,7,8-tetrahydrochromylium fluoroborates, which in turn react with ammonia to give 5-oxo-5,
