Abstract
2-Formyl-8-hydroxyquinoline and 5,7-dimethyl-2-formyl-8-hydroxyquinoline derivatives were synthesized. The use of nitrophenols as the oxidizing agents in the reaction of the appropriate aminophenols with crotonaldehyde leads to a substantial increase in the yields of quinaldines. According to the IR spectroscopic data, the oximes of the formylhydroxyquinolines have a syn configuration.
