3-Acetyl-2,5-dichlorothiophene may be used in the following syntheses:
- substituted chalcones
- AL-4623A and AL-4862 (brinzolamide), inhibitors of topical carbonic anhydrase
- 2,5-dichlorothiophene-3-carboxylic acid, which is the starting reagent required for the synthesis of 2,5-dichloro-N-(substituted amino-carbonothioyl)thiophene-3-carboxamides and 2-(substituted amino)-4H-thieno[3,2-e]-1,3-thiazin-4-ones
| [Definition]
ChEBI: 1-(2,5-Dichloro-3-thienyl)ethan-1-one is an aromatic ketone. | [Synthesis]
1-Methyl-4-chlorobutenal was reacted with a strong base to remove the active hydrogen at the α-position, then docked with thioacetyl chloride and reacted at 60-80 degrees Celsius to obtain the target product 3-acetyl-2,5-dichlorothiophene. |
