摘要 本文研究了在水溶液中γ-环糊精诱导双2-萘甲酸三缩四乙二醇酯(N-P4-N)的分子内光二聚反应.γ-环糊精能够控制N-P4-N光二聚反应的区域选择性和立体选择性,反应只得到反式-头头结构的分子内类立方烷光二聚体,其对映体选择性达20.4%e.e.(在0.5℃时). Intramolecular photodimerization of 2-naphthalene-labeled poly（ethyl glycol） （N-P4- N） induced by γ-cyclodextrin in aqueous solution was investigated. Regioselective and stereose- lective photodimerization of N-P4-N has been demonstrated to be controlled by γ-CD, and thus giving rise to anti-head-to-head intramolecular cubane-like photodimer as the sole product with 20.4% e.e. value.
