Abstract: We investigated the flow of electron density along the cyclocondensation reaction between ethyl acetate 2‐oxo‐2‐(4‐oxo‐4H‐pyrido[1.2‐a]pyrimidin‐3‐yl) polyazaheterocycle (1) and ethylenediamine (2) at the ωB97XD/6–311++G(d,p)computational method within of bond evolution theory (BET). The exploration of potential energy… read more here.
