The synthesis of 7-hydroxy-3,4-dihydro-2- (1H) -quinoline is a key research topic in the field of chemical synthesis. Ancient chemists often followed many paths in synthesizing this compound.
One of them is the reaction of aromatic amines with unsaturated carbonyl compounds. In this case, the double bond or carbonyl of the amino group of the aromatic amine and the unsaturated carbonyl group interact through ingenious chemical changes. The nitrogen atom of aromatic amines is nucleophilic and can attack the lower electron cloud density of unsaturated carbonyl groups. After several delicate reactions such as addition and cyclization, it gradually forms the basic structure of 7-hydroxy-3,4-dihydro-2- (1H) -quinoline. At the time of reaction, careful temperature control is required. If the temperature is too high or too low, the reaction bias and rate are different from expected, or by-products are formed, or the reaction is delayed. And the solvent of the reaction is also very important. The polarity and solubility of different solvents can affect the dispersion of the reactants, the collision frequency and the stability of the transition state. Therefore, a good agent can be selected to promote the reaction.
Second, some compounds containing quinoline parent nuclei are used as starting materials, and the purpose of synthesis can also be achieved through selective reduction and hydroxylation reactions. First, for the raw materials containing quinoline parent nuclei, a suitable reducing agent is used to reduce the specific unsaturated bond. In this step, the dosage of the reducing agent and the reaction timing need to be precisely controlled to avoid excessive reduction. Then, through the action of hydroxylating reagents, hydroxyl groups are introduced at specific positions to achieve 7-hydroxy-3,4-dihydro-2- (1H) -quinoline. However, in this process, the regioselectivity of hydroxylation is a major challenge. In order to make the hydroxyl groups fall accurately at the target position, the reaction conditions need to be considered in detail, such as the pH of the reaction system, the type and dosage of catalysts, etc.
Third, some parties will try to take the cyclization reaction of heterocyclic compounds as the starting point. A specific heterocyclic precursor is used to construct a quinoline ring through cyclization, and then a hydroxyl group is added after subsequent modification to achieve synthesis. In this path, the control of the cyclization conditions is the key. The structure of the reaction substrate and the catalyst used in the reaction have a great impact on the selectivity and efficiency of cyclization. And the subsequent hydroxylation modification also needs to be carefully planned to ensure that the introduction of hydroxyl groups is in line with expectations and does not destroy the constructed quinoline structure.
All these synthetic methods require fine operation and careful regulation by Fang family to achieve the ideal synthesis of 7-hydroxy-3,4-dihydro-2- (1H) -quinoline.
