Nitropyridines as 2π-Partners in 1,3-Dipolar Cycloadditions with N-Methyl Azomethine Ylide: An Easy Access to Condensed Pyrrolines
1,3-Dipolar cycloaddition reactions of 2-substituted 5-<i>R</i>-3-nitropyridines and isomeric 3-<i>R</i>-5-nitropyridines with N-methyl azomethine ylide were studied. The effect of the substituent at positions 2 and 5 of the pyridine ring on the possibility of the [3+2]-cyclo...
