Inherently chiral pyrazine derivative of calixarene was synthesised from calixquinone derivative
and ethylenediamine in the presence of copper (II) acetate as a racemate. The obtained molecule
was characterised by various spectroscopic methods such as: 1H NMR, 13C NMR, HH-COSY and
Keywords: Pyrazine, inherent chirality, copper catalyst, calixarene, michael addition, spectroscopies.
