The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 2-Chloropyridine 1-oxide, is researched, Molecular C5H4ClNO, CAS is 2402-95-1, about [1,4] and [5,5] Thermal sigmatropic rearrangements of 2-pentadienyloxypyridine N-oxides, the main research direction is pyridine oxide pentadienyloxy preparation rearrangement; pentadienyloxypyridine oxide thermal sigmatropic rearrangement; pyridone derivative.HPLC of Formula: 2402-95-1.
2-Pentadienyloxypyridine N-oxides I (R = H, R1, R2 H, Me; R = NO2, R1 = R2 = H) are smoothly transformed on heating into N-pentadienyloxy-2-pyridones II and N-hydroxy-5-pentadienyl-2-pyridones III. These reactions are regiospecific and are believed to proceed in a concerted fashion. The [5,5) sigmatropic rearrangement I → III takes place under moderate conditions and in good yield, although it presumably involves a ten-membered cyclic transition state.
As far as I know, this compound(2402-95-1)HPLC of Formula: 2402-95-1 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
