Tricyclic quinazoline alkaloids are widely distributed in nature. Most often
they occur in the plant
genus
Peganum, Galega, Adhadota, Nitraria, Mackinlaya and others. During 35-40 years at the
Institute of the Chemistry of Plant Substances (ICPS) chemical and
biological activity of
quinazoline alkaloids are studied and among of them many biological active compounds are found.
For example, deoxypeganine hydrochloride is used in medicine as anticholinesterase preparation.
Chemical modification of tricyclic quinazoline alkaloids and their derivatives may open very
interesting direction in the field of fundamental science as well as for developing efficient
preparations in agriculture and medicine. Carrying out of targeted investigation opens widely
possibility to develop of novel potentially active compounds with different biological activity.
Modification of 6-substituted deoxyvasicinones in this work we carried
out synthesis of initial
compound - 6-aminodeoxyvasicinone (
1) by reduction of 6-nitrodeoxyvasicinone with SnCl

. It is
important to note that the 6-aminoderivative in reactions with aromatic aldehydes, depending on the
reaction conditions (solvent, temperature, reaction time and etc.) can form different products on 6-
NH

and 9-CH
