Abstract
SUMMARY
1
This thesis includes three chapters, the first of which
deals with synthesis and reactions of acenaphthenequinone.
Chapter II is a discussion of the work that was carried out by the candidate. The goal of the work is divided into two parts dealing with the synthesis of heterocycles from acenaphthenequinone and furantriones respectively.
Regioisomeric formation of both acenaphtho[1,2—e][1,2,4J-- triazolo[3,4—c][1,2,4]triazines and acenaphtho[1, 2—eJ[1,2,4J-- triazolo[4,3—b][1,2,4]triazines have been achieved in the first part. A model study was carried out in order to confirm the regioselectivity. This study included the synthesis of both isomeric ring systems where the site of fusion in the biheterocycle is [3,4-c) and [4,3—b) as generally represented by 1 and 2 respectively.

The latter type of fusion [4,3—b] was achieved by the condensation of acenaphthenequinoné with 3,4—diainino--5-- methyl—4H-[1,2,4]triazole whereby the linear isomer 10—
