New paper in Organic Letters on anion mediated synthesis of 3-amino-[1,2,4]-triazolo pyridines from our group

Many congratulations to present and former members of our group Komala, Anna, Devis, Jon, Miguel and Salvador for their recent publication, Supramolecular Anion Recognition Mediates One-Pot Synthesis of 3-Amino-[1,2,4]-triazolo Pyridines from Thiosemicarbazides, in Organic Letters!. This work was done through a collaboration of Prof. Gunnlaugsson and Prof. Eoin Scanlan and showed how supramolecular interactions with F (as tetrabutylammonium fluoride, TBAF) of a series of thiosemicarbazides could lead to the formation of 3-amino-[1,2,4]-triazolo pyridines. The synthesis of these heterocycles was obtained in a one-pot reaction from variously substituted hydrazine pyridine and isothiocyanates in the presence of TBAF.
