To prepare 3,4-C-propargyl sugar, 2,5-dialdehyde, 1,4-dioxide, and 3,6-dideoxysugar can be used as raw materials. The synthesis method is as follows:
First, 2,5-dialdehyde is reacted with appropriate reagents. Through ingenious methods, the aldehyde group is converted, condensed, or added to introduce suitable substituents to lay the foundation for the subsequent construction of propargyl sugar structure. This process requires precise control of reaction conditions, such as temperature, pH, and the ratio of reactants. If there is a slight difference, the reaction may be biased to other directions.
Furthermore, 1,4-dioxide participates in the reaction, and its oxidation properties can promote oxidative cracking or rearrangement of chemical bonds at specific locations in the molecule, guiding the reaction to the direction of the target product. Through rational selection of oxidants and reaction media, the oxidation process occurs as expected, and the required functional groups are formed at specific check points of the molecule, which contributes to the construction of propargyl sugars.
And 3,6-dideoxysugar is used in the reaction system as the core skeleton, and its special structure provides support for the final formation of propargyl sugars. By introducing propargyl fragments at their specific positions, this step may require the help of organometallic reagents, etc., ingenious nucleophilic substitution or addition reaction mechanisms can be used to successfully connect propargyl groups to the sugar skeleton.
During the synthesis process, the intermediate products of each step of the reaction need to be carefully separated and identified to ensure that the reaction proceeds according to the plan. And the post-treatment step is also crucial. Appropriate methods need to be used to remove impurities and purify the products in order to obtain high-purity 3,4-C-propargyl sugars. This synthesis method requires familiarity with various reaction mechanisms of organic chemistry and careful design of each step to achieve the goal.

Looking at its physical properties, under room temperature, this substance may be in a solid state. Because of the coexistence of benzene ring and furan ring in its molecular structure, the intermolecular force is strong, so it is mostly solid. And its melting point, boiling point or relatively high, because more energy is required to overcome the intermolecular force, the phase state transition can be achieved.
As for solubility, given that the compound contains hydrophobic groups such as benzene ring, its solubility in water may be extremely low. However, organic solvents, such as dichloromethane, chloroform, toluene, etc., have certain similarities in structure with organic solvents, follow the principle of "similar miscibility", or have good solubility.
In terms of its chemical properties, the benzene ring structure of the substance endows it with certain aromaticity, and can undergo electrophilic substitution reactions such as halogenation, nitration, sulfonation, etc. Although the furan ring part is aromatic, its electron cloud density distribution is different from that of the benzene ring, and its activity is also different. Under appropriate conditions, furan rings can participate in electrophilic addition reactions, and compared with benzene rings, furan rings are more easily oxidized. In addition, due to the existence of multiple cyclic structures in the molecule, the steric resistance effect is significant, which affects its chemical reaction activity and selectivity. In conclusion, the unique molecular structure of 2% 2C5-dioxin-1% 2C4-dioxin-3% 2C6-dibenzofurano [3% 2C4-C] furanine exhibits many special physical and chemical properties, which is of great significance for the research and application in the field of organic chemistry.

How is the compatibility of 2% 2C5-dioxo-1% 2C4-dioxo-3% 2C6-dicarboxylpyridine [3% 2C4-C] pyridine with other materials? This question is related to the key to the compatibility of chemical materials, let me explain in detail.
According to "Tiangong Kaiwu", all materials are compatible and the first weight physical properties are compatible. 2% 2C5-dioxo-1% 2C4-dioxo-3% 2C6-dicarboxylpyridine [3% 2C4-C] pyridine, its molecular structure is unique, and it has specific chemical activities and physical properties. When it comes to hydrophilic materials, if the polarity of the material is adapted, or it can be miscible by hydrogen bond or dipole-dipole action, it presents good compatibility; however, if the polarity is contrary, it is afraid of mutual rejection, and it is difficult to form a homogeneous system.
When it comes to hydrophobic materials, its compatibility is another matter. If the pyridine derivative has hydrophobic groups, it can be blended and compatible with the hydrophobic material or due to van der Waals force. On the contrary, the two or oil and water are distinct.
And the chemical reactivity is also compatible. This pyridine compound contains active groups such as carboxyl groups, and when it comes to active hydrogen or nucleophilic materials, or induces chemical reactions, it is not purely physical mixing. In case of alcohols, carboxylic groups or esterification with them, the original physical properties and compatibility will be changed.
Before metal materials, the pyridine derivatives may complex with metal ions due to their coordination ability, which affects the metal surface properties and the interaction between materials. If the complexation is too strong, or causes metal corrosion and other changes, the stability and compatibility of the material will be damaged.
Therefore, the compatibility of 2% 2C5-dioxy-1% 2C4-dioxo-3% 2C6-dicarboxylpyridine [3% 2C4-C] pyridine with other materials must be carefully investigated. The physical properties, chemical activities and environmental conditions of both parties can be clarified in order to achieve the purpose of reasonable compatibility.

The price trend of 3,4-carbon-vinyl pyridine in the market is a matter of concern to both businesspeople and researchers. According to the theory of "Tiangong Kaiwu", the price of various products is often tied to supply and demand, manufacturing technology and source materials.
As for 3,4-carbon-vinyl pyridine, the amount of supply depends on the actual price. If there are many producers and the market is full of goods, the price will tend to be flat in order to compete for market profits; if the production is thin and the goods should not be demanded, the price will rise. And the art of its preparation is also a major factor. If the craftsmanship is refined, the labor and material are saved, and the yield is increased, the cost can be reduced, and the price will be easy; if the craftsmanship is complicated, the money is laborious, and the cost is high, the price will be high. Furthermore, the abundance of source materials also affects its price. If the source materials are widely available, the price should be light; if the source materials are scarce and difficult to find, the price should be high.
In today's city, 3,4-carbon-vinyl pyridine is used more and more widely, and it has emerged in various fields, and the demand is on the rise. If the supply is not increased rapidly in response, its price may rise. However, with the development of science and technology, there may be breakthroughs in the manufacturing industry. If so, the cost may decrease, and the price may stabilize and decrease. Overall, its price varies in the market, with changes in supply and demand, manufacturing, and source materials. It is in a dynamic state, and it is difficult to determine the number. Only by following the rules of the market can we know its general strategy.
