Facile synthesis of hydrazine derivatives of 5H-pyrrolo[3,4-b]pyrazine and 1H-pyrrolo[3,4-b]quinoxaline

Hordiyenko, Olga V.,Rudenko, Igor V.,Zamkova, Irina A.,Denisenko, Oleksandr V.,Biitseva, Angelina V.,Arrault, Axelle,Tolmachev, Andrei A.

, p. 3375 - 3382 (2014/01/06)

A convenient and efficient route for the chemoselective synthesis of carbohydrazide, arenesulfonylhydrazide, and thiosemicarbazone derivatives of 5H-pyrrolo[3,4-b]pyrazine and 1H-pyrrolo[3,4-b]quinoxaline from the corresponding dinitriles and substituted hydrazines was elaborated. The synthesis of starting pyrazine-2,3-dicarbonitrile was sufficiently improved by using concentrated HCl as a catalyst. Georg Thieme Verlag Stuttgart . New York.
