    通过串联还原-双还原胺化反应将N-苯基取代的吡咯烷,哌啶和氮杂双环
    摘要:
    通过分别在4-和5-氧醛的存在下催化还原硝基苯来合成N-苯基取代的吡咯烷和哌啶。该方法包括还原芳族硝基以得到N-苯基羟胺或苯胺,然后用两个羰基官能团进行还原胺化。单环体系通常以高收率形成并且易于纯化。该方法还扩展到由2-(3-氧代-丙基)环烷酮合成稠合的N-苯基氮杂双环。在具有相对于环烷酮羰基的酯基为α的底物中,观察到对转熔产物的高度非对映选择性。缺少该酯基的双环前体可得到顺式和反式产品。最后,与以前的报道相反,我们证明了在这些反应中苯胺可以代替硝基苯。

    Intramolecular nucleophilic acyl substitution reactions of halo-substituted esters and lactones. New applications of organosamarium reagents
    摘要:
    Intramolecular nucleophilic acyl substitution reactions involving a broad range of halo substituted carboxylic acid derivatives have been accomplished in excellent yield employing samarium(II) iodide as the reductive coupling agent. Although particular substrates cyclized most effectively in THF in the presence of tripiperidinophosphine oxide, carboxylic acid esters, the focus of this report, cyclize equally well without such an additive in the presence of a catalytic quantity of iron(III) complexes. Thus a comprehensive series of halo substituted esters were cyclized in excellent yield to the corresponding 4-, 5-, and 6-membered carbocycles. The reaction is extremely mild and selective as demonstrated by experiments wherein alkyl chlorides, acetals, and olefins remain completely intact under the reaction conditions. In addition to introducing a convenient procedure for preparing stereodefined spirocyclic systems, a new ring expansion sequence has been developed that appears extremely general for the preparation of various ring systems.

  • Mechanistic Study and Development of Catalytic Reactions of Sm(II)
    作者:Sandeepan Maity、Robert A. Flowers

    日期:2019.2.20
    Samarium diiodide (SmI2) is one of the most widely used single-electron reductants available to organic chemists because it is effective in reducing and coupling a wide range of functional groups. Despite the broad utility and application of SmI2 in synthesis, the reagent is used in stoichiometric amounts and has a high molecular weight, resulting in a large amount of material being used for reactions
    二碘化钐 (SmI2) 是有机化学家可用的最广泛使用的单电子还原剂之一,因为它可以有效地还原和偶联各种官能团。尽管 SmI2 在合成中具有广泛的用途和应用,但该试剂以化学计量的量使用并且具有高分子量,导致大量材料用于需要一或多个当量电子的反应。尽管已经设计出开发催化反应的方法很少,但它们并未被广泛使用或需要专门的条件。因此,开发 Sm(II) 催化反应的通用解决方案仍然难以捉摸。在此处,我们报告了使用末端镁还原剂和三甲基氯硅烷以及非配位质子供体源的 Sm(II) 催化反应的机理研究。使用这种方法的反应允许以低至 1 mol% 的 Sm 进行还原。机理研究提供了强有力的证据,表明在反应过程中,SmI2 转化为 SmCl2,从而拓宽了反应的范围。此外,这种机制方法使使用 HMPA 作为配体的催化成为可能,促进了催化 Sm(II) 5- 外向三乙基烯烃环化反应的发展。本文描述的初步工作将有助于进一步开发有用且用户友好的催化反应,这是

    Polycyclic derivatives incorporating a cyclopropyl group have been efficiently synthesized from propargyl acetates using platinum(II), gold(I) and gold(III) catalysis. These reactions which are also viable for the preparation of medium-sized rings, proceed with a complete diastereocontrol and can also be run in neat conditions.
