  从硫代内酯合成中等大小的环醚。在聚醚合成中的应用

  摘要：

  已经制备了多种中等大小的硫代内酯，并与亲核试剂缩合，在用甲基碘淬灭后得到烷基化硫代缩醛。在自由基条件下使用三苯基氢化锡进行还原脱硫可以快速有效地提供相应的环醚，并且在大多数情况下具有完全立体控制。该方法已通过构建短杆菌毒素 A (1) 的 B 环和 D 环模型系统以及 (±)-lauthisan 的合成得到证明

  摘要：

  以RuHCl(CO)(PPh 3 ) 3为催化剂，研究了高烯丙基甲硅烷基醚和碳酸酯的选择性烯烃异构化反应。虽然在氧原子 α 位的芳基或烷基取代基导致选择性转化为烯丙基甲硅烷基醚，但在 α 位没有取代基导致异构化为烯醇甲硅烷基醚。相反，无论 α 位的取代基如何，高烯丙基碳酸酯的异构化都会选择性地生成相应的碳酸烯丙酯。

  alcohols and 2-pyridylmethyl formate in the presence of Ru(3)(CO)(12) initiates a tandem sequence of hydroesterification and lactonization. Mechanistic studies suggest that regioselectivity and overall reaction efficiency are governed by the relative rates of reductive elimination and beta-hydride elimination for the alkylruthenium intermediates.

  A novel design for initiating radical-based chemistry in a catalytic fashion is described. The design of the concept is based on the phenylselenyl group transfer reaction from alkyl phenyl selenides by utilizing PhSeSiR3 (1) as a catalytic reagent. The reaction is initiated by the homolytic cleavage of -C-Se- bond of an alkyl phenyl selenide by the in situ generated alkylsilyl radical (R3Si.), obtained by the mesolysis of PhSeSiR3](.-) (1(.-)). The oxidative dimerization of counteranion PhSe- to PhSeSePh functions as radical terminator. The generation of 1(.-) is achieved by the photoinduced electron transfer (PET) promoted reductive activation of 1 through a photosystem comprising of a visible-light (410 nm)-absorbing electron rich DMA as an electron donor and ascorbic acid as a co-oxidant (Figure 1). The optimum mole ratio between the catalyst 1 and alkyl phenyl selenides for successful reaction is established to be 1:10. The generality of the concept is demonstrated by carrying out variety of radical reactions such as cyclization (10, 15-18), intermolecular addition (25), and tandem annulations (32).

  The investigation presented in this paper explores the mechanistic aspects and synthetic potentials of PET promoted reductive activation of selenosilane la to its radical anion la(-.). PET activation of la is achieved through a photosystem comprising a light-absorbing electron-rich aromatic (ERA), such as DMN or DMA, as an electron donor and ascorbic acid as a co-oxidant. The evidence for the ET from excited singlet states of DMN as well as DMA to la is suggested by estimating negative Delta G(et) (-51 and -43.46 kcal mol(-1), respectively) values and nearly diffusion-controlled fluorescence quenching rate constants (k(q)TR) 0.36 x 10(10) M-1 s(-1) and 0.28 x 10(10) M-1 s(-1), respectively, from time-resolved fluorescence quenching study. The transient absorption spectra of DMN.+, DMA(.+), and la(.-) are obtained initially by pulse radiolysis in order to correlate the time-resolved absorption spectral data. Laser flash photolysis studies in the nanosecond time domain have confirmed the generation of la(.-), DMN.+, and DMA(.+), supporting the participation of the triplet state of DMN or DMA in the ET reaction. Mesolytic cleavage of 1a(.-) produced a silyl radical and a phenyl selenide anion. The preparative PET activation of la in acetonitrile in the presence of DMN or DMA leads to the formation of 5 and 6, confirming the fragmentation pattern of la(.-). The overall ET rate constants (K-r(DMN) = 0.99 x 10(10) M-1 s(-1) and k(r)(DMA) = 1.62 x 10(10) M-1 s(-1)) and limiting quantum yields (phi(lim)DMN) = 0.034 and phi(lim)(DMA) = 0.12) are estimated from the inverse plot (1/[la] vs 1/phi(dis)) Obtained by measuring the dependence of photodissociation quantum yields of la at its maximum concentration in the presence of DMN or DMA. Silicon-centered radical species generated from the mesolysis of la(.-) are utilized for initiating a radical reaction by the abstraction of halogen atom from -C-X (X = Cl, Br) bonds, while PhSe- terminates the radical sequences via PhSeSePh. This concept is successfully applied for the bimolecular group transfer (BMGT) radical reactions and intermolecular radical chain addition reactions.
