THe original work of the submitted thesis explores the utility of tandem generation and 1,5- electrocyclization of N-hetarlnitrilimines for synthesis of novel triheterocyclic systems of biological interest and Dimroth rearrangement of the latter into their isomers.The systems prepared included pyrazolo[4,3-e][1,2,4]triazolo[4,3-c] -pyrimidines and 1,4-disubstituted-[1,2,4] triazolo [4,3-a]-quinazolin-5(4H)-ones
