Synthesis of novel functionalized hydroxyiminoimines by direct nitrosation of β-thio-β-amino-α,β- unsaturated ketones and their further transformations: new general syntheses for imidazole, quinoxaline, and thiazole derivatives

Abstract

New general methods for the synthesis of imidazole (3), (10), quinoxaline (₆), and thiazole (9) derivatives have been developed from the corresponding novel functionalized 1,2-hydroxyiminoimines (2), (5), and (8) obtained by direct nitrosation of β-thio-β-amino-α,β-unsaturated ketones with nitrosyl chloride.
