Purins, pyrimidines, and related condensed systems. 22. Synthesis and heterocyclization of 7-alkynyl- and 6,7-dialkynyllumazines

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
