  摘要：

  在手性 N,N'-二氧化物-Sc(III) 配合物催化剂存在下，实现了外消旋和内消旋环酮的催化对映选择性 Baeyer-Villiger (BV) 氧化。前手性环己酮和环丁酮的 BV 氧化分别提供了一系列具有光学活性的 ε- 和 γ-内酯，产率高达 99%，ee 高达 95%。同时，外消旋 2-芳基环己酮的动力学拆分也是通过异常 BV 氧化实现的。Enantioenriched 3-aryloxepan-2-ones，其形成与迁移能力相反，被优先获得。内酯和未反应的酮均具有高 ee 值。

  有机模型化合物中分子内三重态能量转移的自由能和结构依赖性

  摘要：

  A series of compounds, each containing a triplet energy donor and an acceptor separated by a rigid spacer, has been designed and synthesized. The 1,4-cyclohexanediyl moiety is employed as the spacer for the series. The rates of intramolecular triplet energy transfer (TT) have been measured for the series. The rate of TT shows an inverted parabolic, i.e., Marcus, dependence on the thermodynamic driving force for a selected subset of the compounds wherein the donor is maintained constant throughout and the acceptors are "rigid", having no low-frequency internal degrees of freedom. The internal low-frequency torsional mode of a biphenylyl acceptor can be accounted for quite satisfactorily as an additional contribution to the solvent reorganization energy, lambda-s. The driving force dependence of the rate of TT is not modeled well by the conventional Marcus-Jortner equation for weakly coupled nonadiabatic electron transfer. Generalization of the Marcus-Jortner equation to include coupling to a high-frequency harmonic mode which is both displaced and distorted along the reaction coordinate provides a somewhat better fit to the experimental data with fewer adjustable parameters.

  N'-dioxide-Sc(III) complex catalysts. The BV oxidations of prochiral cyclohexanones and cyclobutanones afforded series of optically active ε- and γ-lactones, respectively, in up to 99% yield and 95% ee. Meanwhile, the kinetic resolution of racemic 2-arylcyclohexanones was also realized via an abnormal BV oxidation. Enantioenriched 3-aryloxepan-2-ones, whose formation is counter to the migratory aptitude, were
