Uses

Used in Medical Applications:
2-AMINO-N-ETHYLBENZENESULFONAMIDE is used as a hemostatic agent for controlling and preventing excessive bleeding in conditions such as menorrhagia, where women experience heavy menstrual bleeding, and to prevent bleeding during and after surgery. It is effective in increasing the strength of blood vessels and decreasing the ability of blood to clot, making it a valuable medication in managing abnormal bleeding.

Palladium(0)-catalysed regioselective cyclisations of 2-amino(tosyl) benzamides/sulphonamides: The stereoselective synthesis of 3-ylidene-[1,4]benzodiazepin-5-ones/benzo[f][1,2,5]thiadiazepine-1,1-dioxides

The Pd(0) catalysed cyclisation reactions betweentert-butyl propargyl carbonates and 2-aminotosyl benzamides or sulphonamides deliver 1,4-benzodiazepin-5-ones or sultam derivatives, key components of many biologically active compounds. But 2-amino benzamides/sulphonamides require propargyl carbonates substituted at acetylenic carbon to undergo the reaction resulting in the stereoselective formation of the said products.

One-pot synthesis ofN-substituted benzannulated triazolesviastable arene diazonium salts

A mild and effective one-pot synthesis of 1,2,3-benzotriazin-4(3H)-ones and benzothiatriazine-1,1(2H)-dioxide analogues has been developed. The method involves the diazotisation and subsequent cyclisation of 2-aminobenzamides and 2-aminobenzenesulfonamidesviastable diazonium salts, prepared using a polymer-supported nitrite reagent andp-tosic acid. The transformation was compatible with a wide range of aryl functional groups and amide/sulfonamide-substituents and was used for the synthesis of pharmaceutically important targets. The synthetic utility of the one-pot diazotisaton-cyclisation process was further demonstrated with the preparation of an α-amino acid containing 1,2,3-benzotriazin-4(3H)-one.

Nickel-catalyzed regio- and enantioselective annulation reactions of 1,2,3,4-benzothiatriazine-1,1(2H)-dioxides with allenes

(Figure Presented) Extrusion of N2:1,2,3,4-Benzothiatriazine1,1 (2H)-dioxides reacted with alienes in the presence of a nickel (0)/(R)-quinap complex to produce a variety of substituted 3,4-dihydro-1,2-benzothiazine1,1 (2H)-dioxides in a regio- and enantioselective fashion. An intermediate nickelacycle was generated through denitrogenative activation of the triazo moiety which allowed the intermolecular incorporation of an aliene group. quinap = 1-(2diphenylphosphino-1-naphthyl)isoquinoline.
