Base induced cyclobutenone rearrangements and its application in the synthesis of aromatic amines
Abstract
A series of fully substituted 2-pyridone 2 and functionalized α-pyrones 3 are synthesized starting from cyclobutenones 1 under a base-promoter in toluene at 80 °C. This rearrangement is complimentary to the previously reported ring expansion of cyclobutenones, providing a divergent synthesis of corresponding products from the same precursor 1. In addition, α-pyrones 3 has also been applied to the synthesis of aromatic amines 7 in good yields...
