###raw material preparation
It is necessary to prepare starting materials with corresponding structures, such as phenyl ring derivatives containing specific substituents, alkenyl compounds, etc. The selection of these raw materials needs to be carefully selected according to the structural characteristics of the target product to ensure that each part of the structure can be accurately docked to construct the target molecule.
###reaction steps
1. ** Construction of carbon-carbon bonds **: Use suitable carbon-carbon bonds to form reactions, such as Suzuki coupling reaction, Heck reaction, etc. If the starting materials are halogenated aromatics and alkenyl borates, and the reaction is heated in an organic solvent in the presence of palladium catalyst, base and suitable ligands, the connection between the benzene ring and the alkenyl moiety can be realized, and an intermediate with a specific double bond position can be formed. This step requires strict control of the reaction temperature, time and the proportion of each reactant to ensure the selectivity and yield of the reaction. For example, under nitrogen protection, halogenated aromatics, alkenyl borates, tetra (triphenylphosphine) palladium, and potassium carbonate are added to the toluene-water mixed solvent in a certain proportion, heated to 80-100 ° C for several hours, and the reaction progress is monitored by TLC.
2. ** Introduction of nitrile groups **: The above intermediates are modified and nitrile groups are introduced by nucleophilic substitution reaction. The halogenated intermediates are reacted with sodium cyanide or potassium cyanide in a suitable polar solvent (such as DMF, etc.) to form new intermediates containing nitrile groups. This process should pay attention to the anhydrous and oxygen-free conditions of the reaction system to avoid the occurrence of side reactions such as cyanide hydrolysis. For example, the halogenated intermediates are slowly added to the DMF solution containing sodium cyanide at low temperature, and the reaction is stirred for a period of time. After treatment, the product containing nitrile groups is obtained.
3. ** Construction of flavonoid acid structure **: Construction of flavonoid acid core structure through reactions such as intramolecular cyclization. Phenolic hydroxyl groups and carbonyl groups can be used for condensation reaction under acid or base catalysis to form flavonate parent nuclei. For example, under basic conditions, intermediates containing phenolic hydroxyl groups and carbonyl groups are heated and refluxed in suitable solvents (such as ethanol, etc.) to promote cyclization. After acidification, extraction and other operations, flavonate intermediates are obtained.
4. ** Esterification reaction **: The flavonoid acid intermediate and butanol are esterified under acid catalysis, and catalysts such as concentrated sulfuric acid or p-toluenesulfonic acid are commonly used. In the presence of water-bearing agent, heating and refluxing promoted the reaction to proceed in the direction of ester formation, and finally obtained the target product (s) -1,2,3,4-tetrahydro-3-isopentenyl flavononitrile ester. After the reaction, the purified product was obtained by separation and purification methods such as neutralization, washing with water, drying, and column chromatography.

(S) -1,2,3,4-tetrahydro-3-isopentenyl flavonoid carboxylate butylactone lactone acid lactone, what is the price of this thing in the market? And answer this question in the ancient classical Chinese style of "Tiangong Kaiwu", about 500 words.
All kinds of things in the world have a price balance. Today, it is difficult to determine the market price of (s) -1,2,3,4-tetrahydro-3-isopentenyl flavonoid carboxylate butylactone acid lactone. The price of this thing is related to many reasons.
First, its origin is also related. If the production is abundant, the source is smooth, the price may be leveled; if the origin is rare, the harvest is difficult, and the source is harsh, the price will be high.
Second, the wide and narrow use is also the main reason. If it is widely used in all industries, or is the key to medicine, or is a heavy material for chemical industry, the price will rise if there are many people who ask for it; if the way to use it is narrow, only suitable for the needs of one or two corners, and there are few people who ask for it, the price will be difficult to be high.
Furthermore, the change of the times can also move the price. When the year is rich, I apologize, and the government is lenient and strict, all of which can be controlled. When the year is rich, the price may be slightly reduced; when the year is sorry, the price will rise. If a government order focuses on its production and sales, and regulates it with complex rules, the cost will increase and the price will increase; if it is relaxed and allowed to circulate, the price may decrease.
There are also businesspeople's plans, which also affect a lot of people. Those who are good at judging the situation, gathering and dispersing goods, and manipulating them. If you stock up and are strange, the price will be high; if you dump it to compete, the price will be low.
In summary, if you want to know the market price of (s) -1,2,3,4-tetrahydro-3-isopentenyl flavonoid carboxylate butyl lactone, you must carefully investigate its origin, consumption, current situation and merchants' plans. However, it is difficult to determine the price without knowing all the feelings today. Only those who look for it can judge the situation and study it carefully in the city to get its near-real price.

(S) -1,2,3,4-tetrahydro-3-isopentenyl flavone butyl acetonolactone acetate acetate, the key to this material is related to its nature and quality. Its sex is delicate and easy to be invaded by light, heat and humidity, so you must be careful when storing it.
It should be placed in a secluded and cool place, away from direct sunlight. Sunlight can promote its transformation and damage its quality. And the temperature must also be suitable, not too high, suitable for room temperature or slightly lower degrees, too high will easily cause its decomposition.
Furthermore, moisture is also a big taboo. Moisture can lead to mildew and decay, so it must be kept dry. The desiccant can be placed next to it to absorb its moisture and protect its quality.
And because it is a chemical agent, or has a certain risk, when hiding, it should be separated from other things to prevent it from mixing and causing danger. And there must be a clear record, note its name, sex, hiding method, etc., so that it can be used and managed. If you hide it properly, the quality of this thing can be preserved for a long time without damage, so that it can be used to the best of its ability when needed.
