First, it can be prepared by condensation reaction from raw materials containing sulfur and methyl. First, take a suitable thiol, and a compound containing methyl and carbonyl groups, and condensate in the presence of a specific catalyst. For example, under the condition of acid or base catalysis, the sulfur atom of the mercaptan is connected to the carbon atom of the carbonyl group, and then the ring is closed to form the basic skeleton of the target product. After appropriate oxidation, the carbon at a specific position reaches the desired oxidation state, and 2-methyl-3-oxytetrahydrothiophene can be obtained.
Second, halogenated hydrocarbons are used as starting materials. Select a suitable halogenated methyl compound and react with a sulfur-containing nucleophile to form a sulfur-containing intermediate. This intermediate reacts with another carbonyl-containing compound to form a tetrahydrothiophene ring system through an intramolecular cyclization step. After that, the substituents on the ring are modified, and the carbonyl group position and oxidation state are adjusted by oxidation and other means to achieve the structure of the target product.
Third, biosynthetic simulation can be used. Drawing on the synthesis pathways of some sulfur-containing compounds in organisms, using enzymes or similar catalytically active substances, under mild conditions, with simple basic structural units such as carbon, sulfur, and methyl, the bionic synthesis of 2-methyl-3-oxytetrahydrothiophene can be gradually spliced and modified. Although this method is challenging, if it is successful, a more green and efficient synthesis pathway may be obtained.
All the above synthesis methods need to be comprehensively considered based on factors such as the availability of raw materials, the difficulty of reaction conditions, and the high and low yield, and optimized by repeated experiments before a practical synthesis strategy can be obtained.
