Access to Fluoroalkylated Azoles and 2-Acylaminoketones {via|by way of|through|by means of} Anhydride-Mediated Cleavage of NH-1,{2|two},3-Triazoles
NH-1,{2|two},3-Triazoles undergo a ring cleavage in reactions with fluorinated acid anhydrides (trifluoroacetic, difluoroaceticchlorodifluoroacetic and pentafluoropropionic anhydrides) by nitrogen acylation and acid-mediated triazole ring opening. Structurally diverse fluoroalkylated oxazoles {were|had been|have…
