A FACILE AND ALTERNATIVE SYNTHESIS OF QUINOLINE NUCLEUS USING THERMAL CYCLIZATION OF 2-AZAHEXATRIENE SYSTEM GENERATED FROM 2-ALKENYL ACYLANILINE WITH POCl3
Hibino, Satoshi,Sugino, Eiichi
, p. 1883 - 1889 (1987)
The thermal cyclization of 2-alkenyl acylanilines with POCl3 in toluene or xylene gave quinoline derivatives in good yield via 2-azahexatriene system in situ.
