Synthesis of sulfonamides pdf

The displacement of the PABA by the sulfonamide leads to the formation of a “false” metabolite in the folic acid synthesis, which cannot continue through the synthetic sequence (Garcia et al., ). Sulfonamides can be classified into three major groups: oral absorbable agents, oral non absorbable agents and topical. Mechanism of sulfonamide action Sulfonamides are competitive antagonists of p-amino- benzoic acid (PABA), the compound essential for the syn- thesis of folic acid, and thus for the bacterial growth and reproduction. Sulfonamides reversibly block the synthesis of folic . The products of each reaction were An Easy Microwave-Assisted Synthesis of Sulfonamides Directly from Sulfonic Acids The Journal of Organic Chemistry. De Luca and Giacomelli Abstract: An easy and handy synthesis of sulfonamides directly from sulfonic acids or its sodium salts is reported.

Synthesis of sulfonamides pdf

Sulfonamides are effective in inhibiting folic acid synthesis due to their structural similarity to PABA. The common structural elements between the two compounds are the benzene rings, para substitution and an amino substitutent.

Synthesis of Sulfanilamide. 4-acetamidobenzenesulfonamide from the previous step is weighed and placed in a 50 mL round-bottom flask equipped with a magnetic stir bar. Dilute hydrochloric acid (6 M) is added to the flask in an amount equal to twice the weight of the 4-acetamidobenzene- sulfonamide. Sulfonamides are effective in inhibiting folic acid synthesis due to their structural similarity to PABA. The common structural elements between the two compounds are the benzene rings, para substitution and an amino substitutent. The acidic sulfonamide group mimics the carboxylic acid functional group of PABA. Sulfonamides via sulfonyl chloride from thiols. Due to the broad applicability of sulfonamides, it is desirable to find general and effective methods for their synthesis. Thus synthesis of these compounds is of continuing interest.
