Ring closing metathesis of 8‐allyl‐9‐butenylpurines or N,9‐diallyl‐N‐methyl‐9H‐purin‐8‐amines with the Grubbs second generation catalyst resulted in fused 9,10‐dihydro‐6H‐azepino[1,2‐e]purines or 9,10‐dihydro‐6H‐[1,3]diazepino[1,2‐e]purines, respectively. The 8‐allyl‐9‐butenylpurines were prepared from 8‐bromo‐9‐butenylpurines after Stille coupling with allyltributyltin. The N,9‐diallyl‐N‐methyl‐9H‐purin‐8‐amines
8-烯丙基-9-丁烯嘌呤或N,9-二烯丙基-N-甲基-9 H-嘌呤-8-胺与Grubbs第二代催化剂的闭环易位导致稠合的9,10-二氢-6 H-氮杂环庚烷[ 1,2-e]嘌呤或9,10-dihydro-6 H- [1,3]二氮杂ze [1,2- e ]嘌呤。Stille与烯丙基三丁基锡偶联后,由8-溴-9-丁烯基嘌呤制备8-烯丙基-9-丁烯基嘌呤。的Ñ,9-二烯丙基ñ -甲基- 9 ħ嘌呤-8-胺从9烯丙基-8- bromopurines处理后H中合成与烯丙胺2在MW辐射下为O,然后在KOH中用MeI甲基化。测试了新化合物作为脂质过氧化抑制剂。6-甲基-4-(吗啉-4-基)-7,10-二氢-6- ħ - [1,3]二氮杂卓并[1,2- ë ]嘌呤呈现有趣的结果,可以作为先导化合物。
