Abstract

The isomeric transition of 2-aminobenzoylhydrazones of aliphatic aldehydes 2-H2NC6H4CONHN=CHAlk (Alk = Me, Et, Pr, Bu) in chloroform-d1 solution into the cyclic 1,2-dihydroquinazolin-4-one form has been studied. The structure of the obtained  compounds was demonstrated by methods of  1H and 13C NMR spectroscopy.
