Chemoselective nitration of aromatic sulfonamides with tert-butyl nitrite.
A methodology for the efficient conversion of aromatic sulfonamides into their mono-nitro derivatives using tert-butyl nitrite is reported. The reaction exhibits a high degree of chemoselectivity for sulfonamide functionalized aryl systems, even in the presence of other sensitive or potentially reactive functionalities.
متن کاملA convenient reductive deamination (hydrodeamination) of aromatic amines.
Reductive deamination (hydrodeamination) of aromatic amines can be conveniently carried out by amination of the corresponding arylamine methanesulfonamides using chloroamine under alkaline conditions. The intermediate aryl methanesulfonylhydrazines directly eliminate methanesulfinic acid, affording diazenes which extrude nitrogen affording the desired deaminated products. Both sulfonamide forma...
متن کاملEfficient one-pot synthesis of pyrazoles catalyzed by nano-crystalline solid acid catalyst
An efficient and green protocol for the synthesis of pyrazoles derivatives by one-pot reaction of different 1,3-dicarbonyl compounds with hydrazines/hydrazides has been developed using nano-sulfated zirconia, nano-structured ZnO, nano-g-alumina and nano-ZSM-5 zeolites, as the catalyst. The optical properties of the nano-structured catalysts and organic molecules were studied. The advantages of ...

متن کاملRegioselective synthesis of nitrosoimidazoheterocycles using tert-butyl nitrite.
A simple and practical method has been developed for the regioselective nitrosylation of imidazopyridines via C(sp(2))-H bond functionalization using tert-butyl nitrite under mild reaction conditions in a short time. A library of 3-nitrosoimidazopyridines with broad functionalities was synthesized in near quantitative yields. The present protocol is also applicable to imidazo[2,1-b]thiazole and...
