A practical method for the synthesis of 2H-imidazoles via a [2+3] annulation of N-H imines with vinyl azides using a copper catalyst is developed. In this conversion, environmentally friendly oxygen is used as the sole oxidant and N2 and H2O are the only by-products. The catalytic transformation, operating under mild conditions, is operationally simple and is considered as a readily available catalytic system having good substrate and functional compatibility with high atom-efficiency without the need for additional ligands or additives.
Photochemistry of Azole N-Oxides. Facile Photoisomerisation of 2H-Imidazole N-Oxides to 1,3-Diaza-6-oxabicyclohex-3-enes and Synthesis of a 1,3-Diaza-4,7-dioxatricyclo1,603,5>heptane

Ultraviolet irradiation of a series of 2H-imidazole N-oxides 2 has been shown to effect a clean isomerization to derivatives of the new ring system, 1,3-diaza-6-oxabicyclohex-3-ene, 7.Epoxidation of a representative 7 has given access to the hither
