| | 2-Mercaptobenzoxazole Usage And Synthesis |
| Chemical Properties | beige crystalline powder | | Uses | 2-Mercaptobenzoxazole is used in the surface treatment of materials. It is utilized for protection of metals from corrosion. | | Preparation | 2-Mercaptobenzoxazole has already been described in 1876 by Dunner (Ber. 9, (1876) page 465). 2-Mercaptobenzoxazole and its derivatives are prepared by processes which are based in principle on the reaction between o-aminophenol and alkali metal alkylxanthates. The alkali metal alkylxanthate here can either be employed as such, or it can be produced in the reaction mixture itself from an alkali, a lower alkanol and carbon disulphide.
https://patents.google.com/patent/US4677209A/en | | Application | 2-Mercaptobenzoxazole is a widely used organic scaffold in medicinal chemistry.
2-Mercaptobenzoxazole and their derivatives are known to posses several biological activities such as antibacterial, antifungal, antiinflammatory, insecticidal and herbicidal. 4-0xo-thiazolidines have also played an important activities as analgesic, anti-HIV, antitubercular, anthelmentic, dye-stuffs, fluorescent and as a photosensitizer. The incorporation of 4-oxothiazolidine and their 5-arylidene moieties in 2-mercaptobenzoxazole frame work has been found to enhance the activity. | | Definition | ChEBI: 2-mercapto-1,3-benzoxazole is a benzoxazole. | | Reactions | 2-Mercaptobenzoxazole with ethyl chloroacetate and anhydrous K2C03 in the presence of dry acetone was refluxed on water bath to give ethyl-2-(mercaptobenzoxazolo)acetate. | | Synthesis | 1. 15 mL of ethanol, 3 mL of water, 10 mmol of o-aminophenol, 10 mmol of carbon disulfide, and 10 mmol of potassium hydroxide were sequentially added to the reaction flask.
2. The reaction mixture was heated to 80 °C and stirred at reflux for 3 hours at this temperature.
3. Upon completion of the reaction, a small amount of zeolite was added to the mixture and filtered while hot.
4. Warm the filtrate to 70 °C and slowly pour it into a beaker containing 10 mL of warm water (preheated to 60-70 °C).
5. cool the beaker in an ice-water bath to induce precipitation of the product.
6. The precipitated white transparent needle-like crystals were collected by filtration and dried to give 1.23 g of 2-mercaptobenzoxazole in 81% yield. | | References | [1] Patent: CN108794421, 2018, A. Location in patent: Paragraph 0024; 0025; 0027
