6,7-Dialkynyl-1,3-dimethylpteridine-2,4(1H,3H)-diones and 2,3-dialkynylquinoxalines have been shown to react with sodium azide in DMF at room temperature giving rise 9,11-dimethyl-[1,2,3]triazolo[1′,5′;1,2]pyrido[4,3-g]pteridine-8,10(9H,11H)-diones and [1

The reaction of 6,7-dichloro-1,3-dimethyllumazine with terminal alkynes under Sonogashira conditions gave 7-alkynyl-6-chloro- and 6,7-dialkynyl-1,3- dimethyllumazines. It was found that the alkynyllumazines readily add primary and secondary alkylamines at
Synthesis and heterocyclizations of 3-alkynyl-6,8-dimethylpyrimido-[4,5-c] pyridazine-5,7(6H,8H)-diones and their lumazine analogues

Synthesis of some condensed pyrrolo-, thieno-, furo-, pyrido- and pyranopteridines as well as isomeric pyrrolo- and thienopyrimido[4,5-c] pyridazines from alkynyl derivatives of 6,8-dimethylpyrimido[4,5-c]pyridazine-5, 7(6H,8H)-dione and 1,3-dimethyllumaz
