Formamidine-Induced Translocative Rearrangement of 2-Pyrones to 2-Pyridone Analogues with a 1,5-Diketo Motif

A new formamidine-induced translocative rearrangement of 2-pyrone analogues into 2-pyridone derivatives with a 1,5-diketo motif was identified. All the products were characterized by spectro-scopic analysis. In addition, single-crystal X-ray structural studies of two molecules were performed.
