2-[(1Z)-1-(4-methylphenyl)-3-(pyrrolidin-1-yl)prop-1-en-1-yl]pyridine

The chemical structure of this substance is quite complex, and I will analyze it in detail. This substance is connected by specific atoms and functional groups in a specific order.
First, its main structure is developed by a core part. Among them, [ (1Z) -1- (4-methylphenyl) -3- (piperidine-1-yl) propyl-1-ene-1-yl], this part is exquisitely constructed. (1Z) The configuration of its double bond is Z-shaped, which means that the larger groups on both sides of the double bond are located on the same side. 1- (4-methylphenyl) indicates that there is a 4-methylphenyl group connected at position 1 of the main chain. This phenyl group is composed of a benzene ring and a methyl group. The methyl group is connected to position 4 of the benzene ring, giving the molecule a specific electronic effect and steric resistance. 3 - (piperidine-1-group) means that piperidine-1-group is connected at position 3 of the main chain. The piperidine ring has a certain rigidity and alkalinity, which has a great influence on the properties of the molecule. Propylene-1-ene-1-yl determines that the main chain is a propyl structure containing double bonds. The existence of double bonds makes the molecule unsaturated and prone to additions and other reactions.
This main structure and other parts together build the unique chemical structure of the substance. The interaction of each part determines the physical and chemical properties of the substance, such as solubility, stability, reactivity, etc. Its unique chemical structure has specific uses and potential value in many fields, or can be used as a key intermediate in the synthesis of other compounds, or in the field of medicinal chemistry. Show unique biological activity.

This question seems to originate from the situation of "Tiangong Kaiwu". The substances involved are complex. Combined with the knowledge of ancient books and the wisdom of the ancients, their main use is as raw materials for alchemy and pharmaceuticals.
In ancient times, alchemy was popular, and many strange substances were included. The substances mentioned here are complex combinations and contain a variety of special ingredients. The ancients believed that they could become miraculous medicinal pills through a specific refining process. Alchemists believe that such medicinal pills may have the effect of prolonging life, strengthening the body, or even making people become immortals. Although there is no scientific basis for the theory of immortality in today's view, at that time, alchemy activities promoted the exploration of material properties and changes.
In addition, the ancients had limited knowledge of substances and often used them in pharmaceuticals. At that time, medical conditions were limited, and various substances were tried to be used as medicine, hoping to cure diseases and save people. Due to its unique composition, this substance was considered to have medicinal value, or had high hopes in the treatment of difficult and complicated diseases. However, due to the technology and cognition at that time, its actual efficacy was difficult to scientifically verify.
In summary, this substance was mainly used in alchemy and pharmaceuticals, reflecting the ancient exploration in the pursuit of longevity and healing. Although it had limitations, it laid the foundation for the development of chemistry and medicine in later generations.

There are many characters and expressions in this text that are difficult to understand. It is speculated that there may be information entry errors or the use of obscure codes or wrong codes in specific fields, etc., resulting in the inability to clarify its exact meaning. It is difficult to answer accurately in classical Chinese form as required. Please check and correct this text carefully to ensure that its meaning is clear and accurate, so that I can provide you with a reply that meets the requirements.

This question seems to be related to the synthesis path of organic chemistry. Although the symbol expression of the question stem is slightly complicated, its structural changes can be sorted out to explore the synthesis method.
For the synthesis of 2- [ (1Z) -1- (4-methylbenzyl) -3- (pyridine-1-yl) propyl-1-alkyne-1-yl] pyridine, it can be analyzed from two aspects: raw material selection and reaction steps.
In the selection of raw materials, in view of the target structure containing pyridine ring, methyl benzyl and alkynyl groups, pyridine derivatives, methyl benzyl-containing structural compounds and alkynyl-containing reagents can be considered as starting materials. For example, suitable substituted pyridine halides and nucleophiles containing alkynyl groups are selected to build a preliminary framework by nucleophilic substitution reaction.
One of the reaction steps is to construct a carbon-carbon triple bond through Sonogashira coupling reaction. Halogenated pyridine and terminal alkynes are used as substrates, and the connection of alkynyl groups to pyridine rings is realized under the action of palladium catalysts, ligands and bases. Second, for the introduction of methyl benzyl moiety, the Friedel-Crafts alkylation reaction can be used. Benzene derivatives (containing methyl) are reacted with halogenated hydrocarbons (side chain halogenates connected to pyridine) under the catalysis of Lewis acid to connect the benzyl group to the appropriate position of the pyridine ring. Third, transition metal-catalyzed cross-coupling reactions, such as Suzuki coupling, can also be used to further optimize the structure and precisely control the position and configuration of the substituent.
The synthesis process requires attention to the fine regulation of reaction conditions, such as temperature, catalyst dosage, reaction time, etc., to ensure that each step of the reaction is efficient and selective. At the same time, attention is paid to the separation and purification of intermediates to ensure the purity and yield of the final product. In this way, multi-method combination and multi-step reaction are expected to achieve the synthesis of the target compound.

I look at what you are asking, the words are obscure, and it seems to be a part of a puzzle. Its expression is ambiguous and many unclear meanings.
Here "2 -% 5B% 281Z% 29 - 1 -% 284 - Ethylbenzyl% 29 - 3 -% 28 p-methoxyacetophenone - 1 - yl% 29 propyl - 1 - ene - 1 - yl", these chemical related names are difficult to determine in the market price range.
Covers chemical products, and their prices vary greatly depending on purity, origin, and supply and demand. And the substances involved in this, if not known in the industry, it is difficult to know their usual market price.
If you want to know the exact price range, you can get the approximate price when you visit a chemical market merchant or consult a professional chemical material trading platform. However, it is difficult to say its price directly based on this vague statement.
You need to study the detailed properties and quality specifications of this thing in detail, and then you can find a more accurate price range in the market.
