    名称:
    Trimethylsumanene: Enantioselective Synthesis, Substituent Effect on Bowl Structure, Inversion Energy, and Electron Conductivity
    摘要:
    通过钯催化对映体纯碘降冰片烯酮的同步选择性环三聚反应、开环/闭环烯烃偏聚反应和氧化芳香化反应(其中 sp3 立体中心传递到碗手性),对映体选择性地合成了 C3 对称手性三甲基马来烯。此外,还实现了衍生物的手性 HPLC 分析/分辨。根据理论计算,苏木烯和三甲基苏木烯的柱状晶包装结构被解释为吸引力静电或 CH-π 相互作用所致。根据实验和理论研究发现,与茱萸烯相比,苏曼烯甲基化时的碗状深度和反转能都会增加。甲基化对苏木烯和芫荽烯的碗状结构和反转能的不同影响被归因于立体斥力的差异。双阱势能模型与取代苏木烯的碗状结构-反转能相关性相拟合,但偏差较小。通过密度泛函理论计算分析了各种取代基对苏曼烯结构和碗状反转能的影响,结果表明碗状刚性是由取代基的电子效应和立体效应共同控制的。采用时间分辨微波传导法研究了三甲基苏马烯的电子传导性,并与苏马烯的电子传导性进行了比较。

    C3 symmetric chiral trimethylsumanene was enantioselectively synthesized through Pd-catalyzed syn-selective cyclotrimerization of an enantiomerically pure iodonorbornenone, ring-opening/closing olefin metathesis, and oxidative aromatization where the sp3 stereogenic center was transmitted to the bowl chirality. Chiral HPLC analysis/resolution of the derivatives were also achieved. Based on theoretical calculations, the columnar crystal packing structure of sumanene and trimethylsumanene was interpreted as due to attractive electrostatic or CH–π interaction. According to the experimental and theoretical studies, the bowl depth and inversion energy were found to increase on methylation for sumanene in contrast to corannulene. Dissimilarities of the effect of methylation on the bowl structure and inversion energy of sumanene and corannulene were ascribed to differences in steric repulsion. A double-well potential model was fitted to the bowl structure–inversion energy correlation of substituted sumanenes, with a small deviation. The effects of various substituents on the sumanene structure and bowl-inversion energy were analyzed by density functional theory calculations, and it was shown that the bowl rigidity is controlled by a combination of electronic and steric effects of the substituents. The electron conductivity of trimethylsumanene was investigated by time-resolved microwave conductivity method, compared with that of sumanene.
