“…α,β-Unsaturated CF 3 -ketones have been shown as versatile building blocks for the synthesis of various fluorinated heterocyclic compounds [36,37,38,39,40]. In a series of works, we have demonstrated a great potential of CF 3 -ynones in different heterocyclizations to prepare fluorinated derivatives of diazepines [41], pyrimidines [42], thiophenes [43], triazoles [44], pyrazoles [45,46,47].…”
