Regiospecific thermal rearrangements of 2-allyloxypyridine N-oxides
Abstract
The results reported of an earlier investigation of the thermal rearrangement of derivatives of 2-allyloxypyridine N-oxide have been shown to be incorrect. Only [1,4] and [3,3] sigmatropic rearrangements are observed and this regiospecificity supports the view that these [1,4] and [3,3] rearrangements proceed by concerted symmetry-allowed pathways.
