Abstract
Based on 2-acetylcyclopentanone, the synthesis of various heterocycles has been studied, in particular, derivatives of pyrazole, pyrimidine, condensed systems of pyrazolo[1,5-a]pyrimidine and 1,2,4-triazolo[1,5-a]pyrimidine, as well as their methyl iodides. Due to the observed nuclear Overhauser effect (NOE), in a number of cases, the structure of the synthesized substances could be proven only by using the NOESY NMR spectroscopy technique. An effective method for using NMR spectroscopy to prove the structures of the synthesized substances is proposed, by obtaining their methyl iodides and then studying the spectra of the resulting salts.
