Ring-opening of cyclic sulfamidates with propargylic sulfonamides yielded substrates for a gold-catalyzed cyclization to yield tetrahydropyrazines. Subsequent reduction or multicomponent reactions of the tetrahydropyrazines gave various piperazine scaffolds, that have a certain value in the synthesis of novel screening compounds with lead-like molecular properties.
