Investigation target - synthesis of new heterocyclic compounds which are pyrrole-2,5-diones, pyrrolidine-2,5-diones, imidazolidine-2,4-diones, phenylhydantoins derivatives based on readily available N-arylaminofumarates and arylglyoxals; structure definition of N,N-substituted carbamates, ureas by X-ray analysis method. Investigation methods - fine organic synthesis, spectroscopic studies. Useful pathways to synthesis of functional derivatives of the mentioned heterocyclic compounds have been developed on the basis of original nitrogen containig reagents. Theoretical regularities of nucleophilic substitution reactions of chlor atom, an alkoxy moiety in ureas, carbamates, tert-alkylamines N-derivatives have been traced. Area of use: production of another chemicals for industrial purposes.
