Synthesis of [1,3]Thiazino[2,3-i]purinium Systems by Halocyclization of 6-(Prenylsulfanyl)- and 6-(But-3-enylsulfanyl)purines

Аннотация

The alkylation of purine-6-thione with prenyl bromide and 3-butenyl bromide in the presence of alkali gave 6-[prenyl(but-3-enyl)sulfanyl]purines which reacted with halogens to afford fused [1,3]thiazino[2,3-i]purinium systems.
