with phenanthroindolizidine alkaloids, contains no nitrogen atom. Attracted by its unique structure and uncovered biological activity, we synthesized the proposed structure of tyloindane and its diastereoisomer. To achieve this goal, several strategies that include an aryl/alkene oxidative coupling, radical cyclization, and intramolecular Parham alkylation, were explored. The 1H NMR data of the synthesized
有趣的是,与菲并吲哚里西啶生物碱一起分离出来的泰洛茚烷不含氮原子。受其独特的结构和未发现的生物活性所吸引,我们合成了所提出的泰洛茚烷及其非对映异构体的结构。为了实现这一目标,探索了几种策略,包括芳基/烯烃氧化偶联、自由基环化和分子内 Parham 烷基化。合成化合物的1 H NMR 数据与分离样品 (tyloindane) 的数据不匹配,表明应该重新分配 tyloindane 的结构。
