For the first time, a method for the synthesis of 2,3-dihydropyrazine 1,4-dioxide derivatives was devised. The presented approach is based on the reaction of N,N′-(2,3-dimethylbutane-2,3-diyl)bis(hydroxylamine) with α-ketoaldehydes. A distinctive feature of the proposed protocol is the application of sulfate of the aforementioned bis-hydroxylamine in the considered condensation. The advantages of the
