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).

关键词: 双-2-萘甲酸酯, 分子内光二聚反应, 类立方烷光二聚体, γ-环糊精, 对映体选择性

Abstract: Intramolecular photodimerization of 2-naphthalene-labeled poly(ethyl glycol) (N-P4-N) induced by γ-cyclodextrin in aqueous solution was investigated. Regioselective and stereoselective 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.

Key words: bis-2-naphthoate, intramolecular photodimerization, cubane-like photodimer, γ-cyclodextrin, enantioselectivity
