Discovery of new chemical reactivity of a given functional group can often result in innovative synthesis of important chemical entities that possess unprecedented properties. We designed and developed a one‐step synthesis of 5‐amino‐4‐carboxamidothiazoles 1 by an yttrium‐triflate‐catalyzed reaction of thiocarboxylic acids 2 with isocyanides 3. In this reaction, both reactants 2 and 3 deviated from...
Die Eintopfsynthese …… von 5‐Amino‐4‐carboxamidothiazolen durch die Yttriumtriflat‐katalysierte Reaktion zwischen Thiocarbonsäuren und Isocyaniden wird von J. Zhu et al. in ihrer Zuschrift auf S. 6699 vorgestellt. Die erhaltenen Heterocyclen sind prototypische Strukturen für den doppelten intramolekularen Protonentransfer im angeregten Zustand (ESIPT) und könnten als Templat für die Synthese von ESICT‐ESIPT‐gekoppelten...
