Synthesis of 1,2,3-triazolo[1,5-a]pyridines
Recent Literature
A heterogeneous copper(II)-catalyzed oxidative cyclization of 2-pyridine
ketone hydrazones was achieved in ethyl acetate at room temperature in the
presence of an MCM-41-anchored bidentate 2-aminoethylamino copper(II) catalyst
and air as the oxidant to provide various [1,2,3]triazolo[1,5-a]pyridines
in good yields. The catalyst can be recovered by filtration and reused at least
seven times.
