Synthesis of 2-Substituted-2,3- dihydro-1,4-dioxino[2,3-b]pyridine Derivatives
摘要:
[GRAPHICS]A variety of 2-substituted-2,3-dihydro-1,4 dioxino[2,3-b]pyridines B have been synthesized from the readily available 2-nitro-3-oxiranylmethoxypyridine 1 via a Smiles rearrangement. We demonstrate how variations of reaction conditions affect the product distribution of A and B.
