In order to prepare 4,5-dihydropyrimido [2,3-c] pyridine-6 (7H) -quinazolinone, there are many ways to synthesize it.
One of them can be obtained by condensation reaction. Take a suitable nitrogen-containing heterocyclic compound with aldehyde, urea or thiourea, and perform condensation reaction under specific catalysts and reaction conditions. Usually Louis acid or Bronster acid are used as catalysts, such as p-toluenesulfonic acid. The reaction temperature and time need to be carefully regulated. If the temperature is too high or side reactions are clustered, if it is too low, the reaction will be delayed. In this process, the structure of the aldehyde has a great influence on the regioselectivity of the product, and it is crucial to select the appropriate aldehyde to obtain the target product.
Second, it is formed by cyclization reaction. Prepare a linear precursor with appropriate functional groups, so that it undergoes intramolecular cyclization under specific conditions. This requires precise design of the structure of the precursor, so that the functional groups interact at the appropriate time and place. For example, the double bond, amino group, carbonyl and other functional groups contained in the precursor are cyclized and rearranged under the action of a base or metal catalyst to construct the desired heterocyclic structure.
Third, the method of multi-component reaction is adopted. A variety of reaction substrates are reacted simultaneously in a pot to build a complex molecular structure in one step. This method has high atomic economy and is easy to operate. However, the proportion of reaction substrates, reaction solvents and reaction conditions need to be properly selected to ensure the efficient progress of the reaction and the purity of the product.
All these methods have their own advantages and disadvantages. The condensation reaction conditions are easier to control, but the selectivity may need to be optimized; the cyclization reaction requires higher synthesis of precursors; although the multi-component reaction is efficient, the reaction parameters need to be fine-tuned. In actual synthesis, the optimal method needs to be weighed according to the availability of raw materials, the purity requirements of the target product, and the cost.
