## Abstract magnified image A new ring‐switching reaction of enaminoesters behaving as bisnucleophiles towards other enaminoesters behaving as biselectrophiles is described. By starting from pyroglutamic derivatives, this reaction provided easy access to methyl 5‐oxo‐1,2,3,5‐tetrahydro‐3‐indolizin
## Abstract Rapid synthesis of 3‐cyano‐4,6‐dimethyl‐2‐pyridone **3**, using piprazine as a catalyst was reported. X‐ray data of the 4,6‐dimethyl‐2‐oxo‐1,2‐dihydropyridine‐3‐carbonitrile exhibited its oxo form. Synthesis of isoquinolinecarbonitrile and pyridylpyridazine using compound **3** was inve
