Synthesis of Densely Substituted Pyridines through 1,2‐Oxazine‐6‐ones Inverse Electron Demand Diels–Alder Reaction

Synthesis of Densely Substituted Pyridines through 1,2‐Oxazine‐6‐ones Inverse Electron Demand Diels–Alder Reaction

Densely substituted pyridines are synthesized from available 1,2‐oxazin‐6‐ones and enamines through tandem hetero‐Diels–Alder and retro‐Diels–Alder reaction in 45–98 % yield. A new simple method for synthesis of densely substituted pyridines from available 1,2‐oxazin‐6‐ones and enamines through tand...
