  固态阳光环化反应的研究：不对称诱导研究和晶体结构-反应性关系

  摘要：

  已在固态和溶液中研究了具有基本顺-4-叔丁基-1-苯甲酰基环己烷或 2-苯甲酰基金刚烷结构的 16 种酮的 Norrish/Yang II 型光化学。在这两种介质中，带有甲基取代基α到苯甲酰基的酮经历立体选择性阳光环化以提供内芳基环丁醇。溶液中的量子产率和猝灭研究表明，这些反应是有效的三重态介导过程。不对称诱导研究是通过为反应物提供羧酸取代基来进行的，“离子手性助剂”通过与旋光胺形成盐而连接到这些羧酸取代基上。溶液中的盐（总共 17 种）的辐照得到外消旋环丁醇，但在结晶状态下，获得了中等至接近定量的对映体过量。对 10 种中性酮和四种盐成功进行了单晶 X 射线衍射研究。这允许识别反应性γ-氢原子并...

  Enhanced Enantio- and Diastereoselectivity via Confinement and Cation Binding:  Yang Photocyclization of 2-Benzoyladamantane Derivatives within Zeolites

  摘要：

  Irradiation of 2-benzoyladamantane derivatives in zeolites yields the endo-cyclobutanols as the only photoproduct via a gamma-hydrogen abstraction process. The cyclobutanols readily undergo retro-aldol reaction to give delta-ketoesters. The enantiomeric excess (ee) in the endo-cyclobutanols is measured by monitoring the ee in the ketoesters. Whereas in solution the ee in the product ketoester is zero, within achiral NaY zeolite, in the presence of a chiral inductor such as pseudoephedrine, ee's up to 28% have been obtained. The influence of zeolite on several chiral esters of 2-benzoyladamantane-2-carboxylic acids has also been examined. Whereas in solution the diastereomeric excess is <15%, in zeolite the delta-ketoesters are obtained in 79% de (best examples). Ab initio computations suggest that enhancement of chiral induction within zeolites is likely to be due to cation complexation with the reactant ketone. Alkali ion-organic interaction, a powerful tool, is waiting to be fully exploited in photochemical and thermal reactions. In this context zeolites could be a useful medium as one could view them as a reservoir of "naked" alkali ions that are only partially coordinated to the zeolite walls.

  investigated in the solid state and solution. In both media, ketones bearing methyl substituents α to the benzoyl group undergo stereoselective Yang photocyclization to afford endo-arylcyclobutanols. Quantum yield and quenching studies in solution show that the reactions are efficient triplet-mediated processes. Asymmetric induction studies were carried out by providing the reactants with carboxylic acid
