Aryl phenol compound as well as synthesis method and application thereof

The invention discloses a synthesis method of an aryl phenol compound shown as a formula (3). All systems are carried out in an air or nitrogen atmosphere, and visible light is utilized to excite a photosensitizer for catalyzation. In a reaction solvent, ArNR1R2 as shown in a formula (1) and water as shown in a formula (2) are used as reaction raw materials and react under the auxiliary action of acid to obtain the aryl phenol compound as shown in a formula (3). The ArNR1R2 in the formula (1) can be primary amine and tertiary amine, can also be steroid and amino acid derivatives, and can also be drugs or derivatives of propofol, paracetamol, ibuprofen, oxaprozin, indomethacin and the like. The synthesis method has the advantages of cheap and easily available raw materials, simple reaction operation, mild reaction conditions, high reaction yield and good compatibility of substrate functional groups. The fluid reaction not only can realize amplification of basic chemicals, but also can realize amplification of fine chemicals, such as synthesis of drugs propofol and paracetamol. The invention has wide application prospect and use value.

Preparation process for 3-methyl-5-methoxybenzenesulfonyl chloride

The invention discloses a preparation process for 3-methyl-5-methoxybenzenesulfonyl chloride. The process comprises the following steps: 3,5-dibromotoluene is used as an initial raw material, the 3,5-dibromotoluene is subjected to a boronic acidification reaction, thus 3-methyl-5-bromophenylboronic acid is obtained, the 3-methyl-5-bromophenylboronic acid is subjected to an oxidation reaction, thus 3-methyl-5-bromophenol is obtained, the 3-methyl-5-bromophenol is subjected to a substitution reaction, thus 3-methyl-5-bromoanisoles is obtained, the 3-methyl-5-bromoanisoles is subjected to sulfonation, thus 3-methyl-5-methoxybenzenesulfonate is obtained, the 3-methyl-5-methoxybenzenesulfonate is subjected to a substitution reaction, and therefore the objective compound 3-methyl-5-methoxybenzenesulfonyl chloride is obtained. According to the above route, the raw materials are easy to obtain, post-treatment is simple, convenient and easy to implement, a yield is relatively high, and the process has relatively-good application value.

Practical one-pot C-H activation/borylation/oxidation: Preparation of 3-bromo-5-methylphenol on a multigram scale

A practical one-pot C-H activation/borylation/oxidation sequence for the generation of 3,5-disubstituted phenols is presented. Specifically, 3-bromo-5-methylphenol is prepared from 3-bromotoluene, without isolation of intermediates, on a multigram scale, and in high yield. The process proceeds under mild conditions and can be completed within one day. Georg Thieme Verlag Stuttgart - New York.
