“…When calculating relatively big molecules, the differences in the energies of conformers can exceed the activation energies of individual stages, and it is necessary to take into account as many variations as possible for each structure in order to separate the conformational energies from the energies of chemical transformations. Only then can the calculated activation barriers of reactions be considered reliable [ 49 , 50 ]. Thus, for all stable compounds, the conformational analysis was performed with the aim to find the global minimum structure or close to it.…”

“…Para a reação de aminólise autocatalítica, o CC passa por quatro intermediários (I1, I2, I3 e I4) para formar o HU, após a formação do I2, vem a etapa responsável pela formação de álcool primário ou secundário. Assim, espera-se uma mistura de hidroxiuretanos primários e secundários ao fim da reação de aminólise 148,149,150.…”
