acene with either N,Ndimethylaminopropylmagnesium chloride or N-methylpiperidinylmagnesium chloride provided the alcohols which could be dehydrated with thionyl chloride/ pyridine to give the silicon analogs of thioxanthene derivatives (SiMe2 replaces S). Several other dehydration attempts are described as well as two other synthetic routes for introduction of an exocyclic double bond in the 10-position
由(o -ClMgC 6 H 4)2 CH 2和二氯硅烷生成的9,10-二氢-9-硅蒽构架为形成包含三环骨架和三原子侧链的衍生衍生物提供了起点。氮基键合至骨架的中心环。酮10-氧代-9,9-二甲基-9,10-二氢-9-硅蒽蒽与N,N二甲基氨基丙基氯化镁或N-甲基哌啶基氯化镁的反应提供了可以用亚硫酰氯/吡啶脱水制得的醇噻吨衍生物的硅类似物(SiMe 2取代S)。描述了几种其他的脱水尝试以及在10位引入环外双键的其他两种合成途径。在H 2 PtCl 6存在下,向N,N-二甲基烯丙基胺中添加9-甲基-9,10-二氢-9-硅蒽蒽的氢化物,然后将9,9-二甲基-9,10-二氢-9-硅蒽蒽溴化与1-甲基哌嗪的反应提供了基于硅烷基蒽骨架的衍生物的另外两个实例。
