Hétérocycles oxygénés (O)

2-Ethylbenzofuran is a benzofuran derivative that has been shown to be a potent inhibitor of acid transport. It is effective in the treatment of gastric and duodenal ulcers, as well as hyperchloremic acidosis. 2-Ethylbenzofuran inhibits the action of calcium carbonate by binding to the active site on rat liver microsomes. This binding prevents the formation of an enzyme-inhibitor complex with polyvinyl chloride, which is required for dibutyl acylation reaction and acidolysis. The drug also blocks acid transporter activity, which may be due to its ability to induce demethylation and inhibit calcium carbonate from forming an enzyme-inhibitor complex with polyvinyl chloride.

Applications 2-(Furan-2-yl)-2-(methoxyimino)acetic Acid is an intermediate in the synthesis of Cephalosporin derivatives.

5-Formylfuran-2-boronic acid is a compound that has been shown to be used in the synthesis of Pd complexes. This compound was found to inhibit the soluble guanylate cyclase and sirtuin 2 enzyme. It also has been shown to have anti-cancer effects, as it may inhibit cancer cell proliferation. 5-Formylfuran-2-boronic acid has been shown to increase the transport properties of potassium dichromate, which may be due to its acidic nature. This red fluorescent compound is soluble in organic solvents and can be activated by light. The optimum concentration of 5-Formylfuran-2-boronic acid is 3 mM in an acidic solution at room temperature.

5-Ethoxy-2(5H)-furanone is an oxidation product of 5-ethoxy-2(5H)-furanone. It has an isomeric, stereospecific, regiospecifically, and a tautomeric relationship with furfural. 5-Ethoxy-2(5H)-furanone can be produced by the oxidation of furfural with boron trifluoride etherate in the presence of iodosobenzene. The reaction mechanism involves the addition of hydrogen peroxide to the boron trifluoride etherate to form hydroperoxydiborane. This compound then reacts with iodosobenzene to produce 5-ethoxy-2(5H)-furanone and 2,5-dihydroxybenzaldehyde. The reaction produces a mixture of diastereomers that contain different numbers of carbon atoms due to the regiospecific

5-Ethyl-4-hydroxy-2-methyl-3(2H)-furanone is a colorless liquid that has a fruity, sweet odor. It is used in the manufacture of flavors and fragrances. 5-Ethyl-4-hydroxy-2-methyl-3(2H)-furanone can be obtained by the reaction of butanedione with dilute sulfuric acid, followed by treatment with an absorber containing propylene glycol and 4-ethyl-2methoxyphenol. The product is then treated with radiation energy to produce furfural, which reacts with anthranilate to form methyl anthranilate. Methyl anthranilate can be converted into phenylmethyl by reacting it with glycosidase.
