  An Experimental and Computational Approach to Defining Structure/Reactivity Relationships for Intramolecular Addition Reactions to Bicyclic Epoxonium Ions

  摘要：

  In this manuscript we report that oxidative cleavage reactions can be used to form oxocarbenium ions that react with pendent epoxides to form bicyclic epoxonium ions as an entry to the formation of cyclic oligoether compounds. Bicyclic epoxonium ion structure was shown to have a dramatic impact on the ratio of exo- to endo-cyclization reactions, with bicyclo[4.1.0] intermediates showing a strong preference for endo-closures and bicyclo[3.1.0] intermediates showing a preference for exo-closures. Computational studies on the structures and energetics of the transition states using the B3LYP/6-31G(d) method provide substantial insight into the origins of this selectivity.

  Highly S_N2′-, (E)-, and Antiselective Alkylation of Allylic Phosphates. Facile Synthesis of Coenzyme Q₁₀

  摘要：

  用烯丙基氯化物或烯丙基磷酸酯在四氢呋喃中与烯丙基格林尼亚试剂及CuCN·2LiCl反应，可以高选择性地生成香叶醇或法尼醇衍生物。磷酸酯的离去基团在生成(E,E)-法尼醇衍生物时表现出高度的反式立体选择性。此外，在光学活性烯丙基磷酸酯的烷基化反应中观察到了完全的反SN2′选择性。该方法似乎是一种优秀的碳-碳偶联反应，具有高的区分选择性、（E）选择性和对映选择性。采用该方法有效合成了辅酶Q10（泛醌10）。

  日期：1995.7

  A new sequence for the highly stereoselective (E>99%) synthesis of a trisubstituted γ,δ-unsaturated acid (3), which consists of a ketal Claisen rearrangement of a terpene allylic alcohol with 2,2-dimethoxy-3-methyl-3-butanol and a subsequent oxidative cleavage of the resulting α-ketol, is applicable even to the preparation of 3 which is difficult to synthesize by traditional methods. The related procedure

  Treatment of secondary allylic chlorides or allylic phosphates in tetrahydrofuran with prenyl Grignard reagent in the presence of CuCN · 2 LiCl gave geraniol or farnesol derivatives with high SN2′ selectivity. Phosphate leaving groups were highly trans-stereoselective for the formation of (E,E)-farnesol derivatives. Furthermore, complete anti-SN2′ selectivity was observed in the alkylation of optically active allylic phosphates. The present method appears to be an excellent carbon-carbon coupling reaction with high regio-, (E)-, and enantioselectivity. Coenzyme Q10 (ubiquinone 10) was efficiently synthesized using this methodology.
