Abstract
The data on nucleophilic substitution reactions of hydrogen in 6,8-dimethylpyrimido[4,5-c]pyridazine-5,7(6H,8H)-dione, its 3-chloride, N2-oxide and some other derivatives are reviewed. All these compounds possess a remarkable ability to undergo not only simple functionalizations but also tandem and cascade transformations leading to annelation of various heterocyclic rings.
