Autor: Adel’ P. Kriven’ko, Darya M. Demidova, Natalia O. Vasil’kova
Publikováno v: Izvestiya of Saratov University. New Series. Series: Chemistry. Biology. Ecology. 21:128-133
Aryl-substituted triazolohexahydroquinazolines have been synthesized by means of three-component condensation of pnitro(pbromo) benzaldehydes, cyclohexanone, 1,2,4-triazol-3-amine. A scheme of the reaction mechanism is proposed, which makes it possib
