Facile synthesis of novel 3,4,5-trisubstituted-1,2,4-triazin-6(1H)-ones via a sequential Ugi-Smiles type/nucleophilic substitution/cyclization reaction
A simple and innovative strategy is described for synthesizing a library of novel 3,4,5-trisubstituted-1,2,4-triazin-6(1H)-one backbones in mild conditions. This approach involves multiple bond-forming events in an Ugi-Smiles type reaction and the post-condensation of the Ugi-Smiles adduct incorpora...

| Riassunto: | A simple and innovative strategy is described for synthesizing a library of novel 3,4,5-trisubstituted-1,2,4-triazin-6(1H)-one backbones in mild conditions. This approach involves multiple bond-forming events in an Ugi-Smiles type reaction and the post-condensation of the Ugi-Smiles adduct incorporating a series of electron-withdrawing substituted benzaldehydes, primary amines, saccharin, and isocyanides followed by the addition of hydrazine hydrate for the post-condensation step. |
