Simple and green synthesis of 3-acyl-pyrazolo[1,5-a]pyridines: [3+2] through cycloaddition of N-aminopyridines on enaminones
A practicable method is described for the synthesis of 3-acyl-pyrazolo[1,5-a]pyridines from N-aminopyridines and easily available enaminones via a [3+2] cycloaddition. The reactions proceed well with a broad scope, without using additive (base or oxidant).
期刊介绍：
The Journal of Heterocyclic Chemistry is interested in publishing research on all aspects of heterocyclic chemistry, especially development and application of efficient synthetic methodologies and strategies for the synthesis of various heterocyclic compounds. In addition, Journal of Heterocyclic Chemistry promotes research in other areas that contribute to heterocyclic synthesis/application, such as synthesis design, reaction techniques, flow chemistry and continuous processing, multiphase catalysis, green chemistry, catalyst immobilization and recycling.
