The reaction of primary and secondary amines with benzenesulfonyl chloride is the basis of the Hinsberg reaction, a method for detecting primary and secondary amines. Sulfonamides undergo a variety of acid-base reactions. The N-H bond can be deprotonated. The alkylsulfonamides can be deprotonated at carbon. Arylsulfonamides undergo ortho ...
Sulfonamide functional group Hydrochlorothiazide is a sulfonamide and a thiazide. Furosemide is a sulfonamide, but not a thiazide. Sulfamethoxazole is an antibacterial sulfonamide. Sulfonamide is a functional group (a part of a molecule) that is the basis of several groups of drugs, which are called sulphonamides, sulfa drugs or sulpha drugs.
A novel variant of the Appel reaction has been noted for sulfenamides. Reaction of o-nitrobenzenesulfenamide with PPh 3 and CCl 4 leads the formation of o-nitro-N-(triphenylphosphorany1idene)-benzenesulfenamide. In this variant reaction, the triphenyl phosphine forms a double bonded linkage with nitrogen in the sulfenamide instead of oxygen as ...
Prontosil is an antibacterial drug of the sulfonamide group. It has a relatively broad effect against gram-positive cocci but not against enterobacteria.One of the earliest antimicrobial drugs, it was widely used in the mid-20th century but is little used today because better options now exist.
Sulfanilamide (also spelled sulphanilamide) is a sulfonamide antibacterial drug. Chemically, it is an organic compound consisting of an aniline derivatized with a sulfonamide group. [1] Powdered sulfanilamide was used by the Allies in World War II to reduce infection rates and contributed to a dramatic reduction in mortality rates compared to ...
The reaction leads to 1,2,3,4-tetrahydroquinoline derivatives and is a good preparative method of six-membered cyclic aromatic amines. For instance, sulfonamide 78 undergoes an intramolecular radical cyclization to afford 79 in relatively good yield.
Chemical structure of a generic acylsulfonamide. Acylsulfonamide is a functional group in organic chemistry that is sometimes used in medicinal chemistry. [1] It consists of a sulfonamide group (SO 2 NH) linked to an acyl group (RCO), forming the structure R 1-CO-NH-SO 2-R 2.
The reaction is used in a chemical test for the detection of aldehydes in combination with ferric chloride. In this test a few drops of aldehyde containing specimen is dissolved in ethanol, the sulfonamide is added together with some sodium hydroxide solution and then the solution is acidified to Congo red. An added drop of ferric chloride will ...
