What are the synthesis methods of 1- [5- (2,6-difluorophenyl) -4,5-dihydro-1,2-oxazole-3-yl] ethyl ketone?

To prepare 1 - [5- (2,6-diethylphenyl) -4,5-dihydro-1,2-oxazole-3-yl] acetamide, the synthesis method is as follows:

The starting material can be selected from a compound containing 2,6-diethylphenyl, and the introduction of this group has a key impact on the structure and properties of the product. 2,6-diethylphenyl can be connected to the aromatic ring by Suzuki coupling reaction with suitable halogenated aromatics and diethylbenzene in alkali and palladium catalyzed systems. For example, using p-halobenzaldehyde and diethylphenylboronic acid as raw materials, potassium carbonate as base, tetrakis (triphenylphosphine) palladium as catalyst, and heating and refluxing in a toluene-water mixed solvent can efficiently construct 2,6-diethylphenyl substituted aromatic aldehyde structures.

Subsequently, the obtained 2,6-diethylphenyl-containing aromatic aldehyde is reacted with suitable nitrogen sources and enolization reagents to prepare 4,5-dihydro-1,2-oxazole structures. For example, the aromatic aldehyde reacts with hydroxylamine hydrochloride in pyridine to form an oxime, and then reacts with enolizing reagents such as acetylmagnesium bromide at low temperature to form a 4,5-dihydro-1,2-oxazole ring through cyclization.

After constructing the oxazole ring, it is modified to introduce acetamide groups. Nucleophilic substitution reactions can occur with acid chloride or anhydride and suitable check points on the oxazole ring. If acetyl chloride is used as an acylating reagent, under the catalysis of triethylamine and other bases, it reacts in a dichloromethane solvent, and the acetyl group is introduced into the oxazole ring to generate the target product 1 - [5- (2,6-diethylphenyl) -4,5-dihydro-1,2-oxazole-3-yl] acetamide.

The whole process of synthesis requires precise control of reaction conditions, such as temperature, reaction time and reagent dosage. After the reaction, the product is purified by means of column chromatography, recrystallization, etc., to improve the purity of the product. Through clever design and fine operation of each step, the target compound can be effectively synthesized.

What is the market price of 1- [5- (2,6-difluorophenyl) -4,5-dihydro-1,2-oxazole-3-yl] ethanone?

There is a question about the price of one price today, which is related to the market price of 1 - [5 - (2.6 - divinyl) -4.5 - dioxide - 1.2 - malodorous - 3 - base] acetic anhydride. However, in order to understand this question, there is still a lack of key information, such as its manufacturing cost, supply and demand status, quality level, and market competition.

If you think about it in the way of "Tiangong Kaiwu", the price of everything is determined by many factors. In terms of manufacturing costs, if the raw materials are rare and rare, or the manufacturing techniques are complicated and laborious, the price will be high and the price will rise accordingly. Looking at supply and demand, if there are many people seeking this product in the market, but there are few suppliers, the price will rise; on the contrary, if the supply exceeds the demand, the price will naturally decline. Quality is also important, and the price of fine products will be higher than that of poor products. And the slowdown in market competition can also make the price different. If there are many competitors in the same industry, the price may be leveled to compete for market profits.

It is difficult to determine the market price of 1 - [5 - (2.6-divinyl) -4.5-dioxide-1.2-malodorous-3-base] acetic anhydride. Only by knowing the above can we obtain a more accurate price.
