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.
在碱存在下,用异戊烯基溴化物和3-丁烯基溴化物将嘌呤-6-硫酮烷基化,得到6- [异戊烯基(but-3-enyl)ulfanyl] purines与卤素反应生成稠合的[1,3]噻嗪[ 2,3- i ] pur系。
