To obtain the synthesis method of (2,6-naphthalene-pyridinedione, 4,5,6,7-tetrahydro-N (subscript 6) -methyl- (S) -propyl), the following method can be used.
Naphthalene is first taken as the starting material, and the structure of pyridinedione is introduced under specific reaction conditions. This step requires fine regulation of the reaction temperature, pH and the ratio of the reactants. Naphthalene and specific reagents can gradually form the basic structure of naphthalene-pyridinedione in a suitable organic solvent and catalyzed by a specific catalyst.
Then, for the formation of the structure of 4,5,6,7-tetrahydro, a suitable hydrogenation reagent needs to be selected. Metal hydrides such as sodium borohydride or lithium aluminum hydride can be used to hydrogenate the above products under low temperature and inert gas protection. When hydrogenating, close attention should be paid to the reaction process to prevent excessive hydrogenation from impurities of the product.
As for the introduction of N (subscript 6) -methyl, methylating reagents can be selected, such as iodomethane or dimethyl sulfate. Under alkaline conditions, the above hydrogenation products undergo nucleophilic substitution reactions with methylating reagents. The strength of the alkalinity and the length of the reaction time have an important impact on the methylation effect.
Finally, the access of (S) -propyl can be synthesized by chiral synthesis. First, a propyl reagent with (S) -configuration is prepared, and it is used to react with the product containing the aforementioned structure, or to induce the reaction through a chiral catalyst to achieve the purpose of introducing (S) -propyl precisely. During the whole synthesis process, the separation and purification of intermediate products must be properly handled between each step of the reaction in order to obtain high-purity target products.

In "Tiangong Kaiwu", among the various objects, 2,6-naphthalene-pyridinedione, 4,5,6,7-tetrahydro-N (subscript 6) -methyl-, (S) -this number of objects, are there those that sink in the wind vortex?
In view, 2,6-naphthalene-pyridinedione has a specific chemical structure and properties. Its molecular structure is unique, so that its physical and chemical properties are different from those of ordinary substances. However, in the wind vortex environment, if its density is greater than that of the surrounding medium, or if it is affected by the wind force in a special way due to the structure, it may theoretically sink in the wind vortex.
As for the 4,5,6,7-tetrahydro-N (subscript 6) -methyl- (S) -object, its specific physical properties also need to be investigated. If the density of this object is large, and in the flow field environment involved in the wind vortex, the buoyancy is less than gravity, and the wind is not enough to blow it away, it is very likely to settle in the wind vortex.
In the wind vortex, the air flow disorder is complex, and the fluctuation of the object depends not only on the density, but also on the shape, surface properties and specific flow patterns of the wind vortex. If the shape of the object is conducive to the lift of the airflow, even if the density is slightly higher, it may be suspended; conversely, if the shape is easy to cause the airflow to peel off, even if the density is not large, there is a risk of settlement. If the surface properties are rough, the friction with the airflow will increase, which will also affect its motion state in the wind vortex.
In general, 2,6-naphthalene pyridyl dione, 4,5,6,7-tetrahydro-N (subscript 6) -methyl- (S) -under specific conditions, it is possible to sink in the wind vortex, but it is necessary to consider its physical properties and the specific environment of the wind vortex before concluding.
