The preparation of 2-substituted-3-diazoquinolin-4-ones
摘要:
A series of 2-substituted-3-diazoquinolin-4-ones is prepared by the reaction of 2-substituted-3-amino-4-chloroquinolines with sodium nitrite in sulfuric acid. Some of the obtained products are then utilised in triazole formation, reduction and a Wolff rearrangement/Friedel-Crafts ketene capture. (C) 2014 Published by Elsevier Ltd.
Preparation and Reactivity of 3-Amino-2,4-dichloroquinoline
摘要:
A simple and efficient synthesis of 2-substituted 3-amino-4-chloroquinolines and 2,4-disubstituted 3-aminoquinolines was carried out by reacting 3-amino-2,4-dichloroquinoline with various oxygen-, sulfur-and nitrogen-containing nucleophiles.
