To prepare 2-pentyne-5-methyl-3-hexenoic acid, the following ancient methods can be used.
First, start with the corresponding halogenated hydrocarbon. First, take a suitable halogenated alkene and make it nucleophilic substitution reaction with sodium alkyne. The preparation of sodium alkyne can be obtained by reacting alkyne with sodium metal in a suitable solvent such as liquid ammonia. When the halogenated alkyne meets the sodium alkyne, the halogen atom leaves, and the alkynyl group is substituted to obtain an intermediate containing the alkynyl group and the alkenyl group. Subsequently, this intermediate is reacted with carbon dioxide under suitable conditions, and after acidification treatment, carboxyl groups can be introduced to obtain the target product 2-pentyne-5-methyl-3-hexenoic acid. This process requires attention to the precise control of the reaction conditions, such as temperature and solvent selection, to ensure that the reaction proceeds in the desired direction.
Second, starting from the enol compound. The enol can be protected by a suitable protective group to prevent it from reacting without end in the subsequent reaction. Afterwards, the enol derivative and the alkyne derivative are coupled under the action of a specific catalyst. This catalyst may be a transition metal complex or the like. After the reaction is completed, the protecting group is removed, and then the enol is converted into carboxylic acid through an oxidation step, which can also achieve the purpose of preparing 2-pentyne-5-methyl-3-hexenoic acid. In this path, the selection and removal of the protecting group, as well as the consideration of oxidation conditions, are very important, which are related to the purity and yield of the product.
Third, consider aldosteroids as starting materials. Aldosteroids can first undergo nucleophilic addition reaction with alkynides to obtain alcohols containing alkynyl groups. Subsequently, the alcohols are dehydrated to form alkynes. 2-Pentyne-5-methyl-3-hexenoic acid is obtained by oxidizing the alcohol hydroxyl group to carboxylic group with suitable oxidant. In this route, the selectivity of nucleophilic addition, the conditions of dehydration reaction and the control of oxidation reaction are all key factors for successful preparation, which need to be carefully considered and handled with caution.

Today there is 2-hydroxy-5-methyl-3-nitrobenzoic acid, and you want to know its price range in the market. This compound may have specific uses in the chemical industry, but its price often varies depending on factors such as quality, supply and demand, origin, and purchase volume.
If the quality is high, the purity is very high, and the purchase volume is small in the peak demand season, the price may be high. On the contrary, if the quality is ordinary, the market supply is sufficient, and the purchase volume is large, the price may be relatively easy.
According to past market conditions and general market speculation, in the general chemical raw material trading market, small batch purchases, with a purity of about 95%, the price per gram may range from tens of yuan to hundreds of yuan; if it is industrial grade, the purity is slightly lower, and a large number of purchases, the price per kilogram may be around thousands of yuan. But this is only a rough estimate, and the actual price should be subject to the current quotations of various suppliers. To get an accurate price, you can consult chemical product suppliers and online chemical trading platforms for detailed comparison before you can know the exact price.
