Es wird die Synthese einiger O-substituierter 4-Chinolinole und 5,6,7,8-Tetrahydro-4-chinolinole 7–13 beschrieben. Ausgehend von 2 und 4 gelangt man mit POCl3 zu 4-Chlorchinolinen 14 und 15, welche in die 4-Aryloxychinoline 16 und 17 sowie 4-Alkyl-(Aryl-)thiochinoline 20 bzw. 4-Aminochinoline 21 übergeführt werden.
A metal catalyst free approach for regioselective ortho-chlorination of anilines has been developed using a secondary amine as the organocatalyst and sulfuryl chloride as the halogen source under mild conditions. A wide range of substrates were compatible with this catalytic system. In addition, this catalytic protocol has been applied to the efficient synthesis of bioactive compounds and modification
