title: Synthesis of pyrazines from rhodium-catalyzed reaction of 2H-Azirines with N-sulfonyl 1,2,3-triazoles.
abstract: An efficient synthetic route to a wide range of trisubstituted pyrazines is developed from Rh-catalyzed reaction of 2H-azirines with N-sulfonyl-1,2,3-triazoles through the elimination of nitrogen molecule and arylsulfinic acid. The present reaction proceeds through formation of in situ generated dihydropyrazines.
