Molecular Rearrangements of 1-Oxa-2-azoles as an Expedient Route to Fluorinated Heterocyclic Compounds

摘要: Molecular rearrangements of O-N bond-containing azoles (1-oxa-2- azoles) represent a wide class reactions by which various heterocycle-to- heterocycle transformations can be performed as alternative synthetic methodologies. The material presented in this review is an extensive survey both thermal and photochemical methodologies that have been applied to fluorinated oxadiazoles, shows how molecular some cases the most convenient route for synthesis several heterocycles.
