The Azomethine Group was formed in 1994 and transformed into a laboratory in 2012. During this period, the laboratory was headed by  Doctor of Chemical Sciences Mushegh S. Sargsyan. In 2023, it became a group again. Since then, it has been led by Anush Kh. Khachatryan, who has a PhD in Chemistry and is an Associate Professor who continues the main area of research – studying the interaction between active electrophilic alkenes containing electron-accepting groups and active methylene compounds.

MAIN RESEARCH DIRECTION

Studies in Organic Synthesis

  • Study of the interaction of imines, electrophilic alkenes (chalcones) and nucleophiles (C-H acids) containing an amide group,
  • Study of the regioselectivity of the intramolecular cyclization of intermediates obtained as a result of the Michael reaction, including analysis of the possibilities of the Michael retro-reaction.

Synthesis of New Organic Systems

  • Synthesis of multifunctional substituted carbo- and azacyclic compounds,
  • Study of the biological properties of the obtained products.

BEST RESULTS

  • The chemoselectivity of the reaction between araldimines and arylamides of acetoacetic acid has been revealed. It has been shown that intramolecular cyclization, depending on the electronic nature of the substituents present in the starting molecules, proceeds with the formation of either 3-aryl-N,6-diaryl-3-hydroxy-1,3-dimethyl-5-oxo-2-oxa-6-azabicyclo[2,2,2]octane-7-carboxamides (in the heterocycle) or 4-hydroxy-4-methyl-6-oxo-2-aryl-N1,N3-diarylcyclohexane-1,3-dicarboxamides (in the carbocycle), or a mixture thereof.

Chem. J. Armenia, 2015, v. 68, № 2, pp. 266-275

  • It has been shown that the reaction of ethyl 6-aryl-5-(arylcarbamoyl)-2-hydroxy-2-methyl-4-oxocyclohexanecarboxylates with hydroxylamine hydrochloride, in addition to the expected corresponding oximes, in some cases also leads to the formation of ethyl 4-hydroxy-4-methyl-6-oxo-2-arylpiperidine-3-carboxylates. A separate experiment confirmed that the latter are not formed from the starting cyclohexanes, but are the result of the subsequent reaction of the corresponding oximes with hydroxylamine hydrochloride.

Chem. J. Armenia, 2021, v. 74, № 1-2, pp. 113-121

  • A method for obtaining diethyl 6-amino-1,4-diaryl-2-oxo-1,2,3,4-tetrahydropyridine-3,5-dicarboxylates from the interaction of arylmethylidenedianacetic acid esters and arylamidoesters of malonic acid has been developed.
