What are the synthesis methods of 2-Quinolineethanol?

The synthesis method of 2-quinoline ethanol has been known in ancient times, and now it is detailed by Jun Chen.

First, quinoline is used as the base, and the nucleophilic substitution method is used. First, quinoline and halogenated ethanol are reacted at co-temperature in suitable bases and solvents. Base agents such as potassium carbonate can promote the departure of the halogen atom of halogenated ethanol, while the nitrogen atom of quinoline is attacked nucleophilically, and then it becomes 2-quinoline ethanol. This reaction needs to be controlled by temperature. If the temperature is too high, side reactions will occur, and if it is too low, the reaction will be delayed.

Second, the method of metal catalysis is used. Transition metal catalysts, such as palladium, are used to catalyze the reaction of quin The metal catalyst can activate the substrate and greatly increase the reaction activity. In this process, aptamers need to be selected to increase the selectivity and activity of the catalyst. The reaction is carried out under the protection of inert gas to prevent the oxidation of the metal catalyst from deactivation.

Third, it is converted from quinoline derivatives. First, quinoline derivatives containing convertible groups, such as quinoline aldehyde or quinoline one, are prepared. Taking quinoline aldehyde as an example, it can be converted into 2-quinoline ethanol through a series of reactions such as reduction and hydroxylation. Strong reducing agents such as lithium aluminum hydride are commonly used in the reduction step, and suitable reagents and conditions are selected for hydroxylation according to specific conditions. < Br >
This number method has its own advantages and disadvantages, and the practical application depends on factors such as raw material availability, cost and reaction conditions.
