  Copper-Catalyzed Allylation of Carbonyl Derivatives Using Allyl(2-pyridyl)silanes

  摘要：

  We have developed an efficient copper-catalyzed allylation of carbonyl derivatives using allyl(2-pyridyl)si lanes, in which the strong directing effect of the 2-pyridyl group was observed. A useful synthesis and allylation of substituted allyl(2-pyridyl)si lanes is also described.

  diastereoselective addition of gamma-substituted allylic nucleophiles to ketones has been accomplished to give tertiary homoallylic alcohols. The reaction of tributylcinnamyltin 1a with simple ketones 2 in the presence of stannous chloride (SnCl(2)) gave the tertiary homoallylic alcohols 3, which include the anti form (based on Ph and OH), with high diastereoselectivity. In the reaction course, transmetalation

  γ-取代的烯丙基亲核试剂与酮的非对映选择性加成得到了叔高烯丙基醇。在氯化亚锡 (SnCl(2)) 存在下，三丁基肉桂基锡 1a 与简单酮 2 的反应得到叔高烯丙醇 3，其中包括反形式（基于 Ph 和 OH），具有高非对映选择性。在反应过程中，三丁基肉桂基锡 1a 与 SnCl(2) 进行金属转移，形成活性亲核试剂，暂时认为是肉桂基锡 (II) 物种。环状过渡态 A 是有利的，因为氯化锡 (II) 中心非常能够接受配体。通过使用 BF(3) x OEt(2) 而不是 SnCl(2)，在三丁基肉桂基锡 1a 与酮 2 的反应中获得其他非对映异构体（syn 形式）4。该反应通过无环过渡状态进行，其中 BF(3) 充当路易斯酸以激活酮。当 3-三丁基甲锡烷基环己烯 1b 或 3-三丁基甲锡烷基环戊烯 1c 与 SnCl(2) 一起使用时，观察到具有顺式（基于环链和 OH）的相应高烯丙基醇 6 的高非对映选择性形成。选择性也由环状过渡态
• Facile Preparation of Allylzinc Species from Allyl Bromides and Unactivated Zinc Induced by a Catalytic Amount of Aluminum Chloride and Their Reactions with Carbonyl Compounds and Acetals.

  The effects of Lewis acids (ZnCl2, AlCl3, BF3, and TiCl4) on the generation of allylzinc species from allyl bromide and unactivated zinc powder in dry tetrahydrofuran (THF) were examined by trapping the organozinc compound with benzaldehyde, that is, Grignard-type allylation of the aldehyde. Among the Lewis acids employed, AlCl3, was found to be the promoter of choice. The allylzinc species preformed in the presence of a catalytic amount of AlCl3 effectively allylated carbonyl compounds. Various aromatic and aliphatic aldehydes as well as ketones were converted into homoallylic alcohols in good to excellent yields. Under the reaction conditions employed, ester, hydroxy, acetal, and aromatic nitro and halide groups were tolerated. In the case of α, β-unsaturated carbonyl compounds, selective 1, 2-addition was observed. Substituted allyl bromides such as prenyl, crotyl, cinnamyl, and 2-cyclohexenyl bromides were smoothly converted to the corresponding allylzinc compounds, which reacted with carbonyl compounds to give substituted homoallylic alcohols in excellent yields. The diastereoselectivity in crotylation, cinnamylation, and 2-cyclohexenylation depended upon the structures of both the organic metals and the electrophiles. The origin of the observed selectivity is discussed. The allylation of dimethyl and cyclic acetals accompanied with carbon-oxygen bond cleavege also proceeded in excellent yields provided that two equivalents of AlCl3 was present.

  在干燥的四氢呋喃（THF）中，研究了路易斯酸（ZnCl2、AlCl3、BF3和TiCl4）对烯丙基溴和未活化的锌粉生成烯丙基锌物种的影响，并通过苯甲醛捕获有机锌化合物，即醛的格氏型烯丙基化反应。在所用的路易斯酸中，AlCl3被发现是最优的促进剂。在催化量的AlCl3存在下预形成的烯丙基锌物种能有效地烯丙基化羰基化合物。各种芳香族和脂肪族醛以及酮被转化为同烯丙基醇，产率良好至优秀。在所采用的反应条件下，酯、羟基、缩醛以及芳香族硝基和卤素基团均被容忍。对于α,β-不饱和羰基化合物，观察到了选择性的1,2-加成。取代的烯丙基溴如香叶基、巴豆基、肉桂基和2-环己烯基溴均能顺利转化为相应的烯丙基锌化合物，这些化合物与羰基化合物反应生成取代的同烯丙基醇，产率极佳。在巴豆基化、肉桂基化和2-环己烯基化中的立体选择性取决于有机金属和亲电试剂的结构。讨论了观察到的选择性的起源。在AlCl3的两当量存在下，伴随着碳-氧键断裂的二甲基和环状缩醛的烯丙基化也以极佳的产率进行。

  was designed by integration of the pincer-complex-catalyzed borylation of allyl alcohols in the Petasis borono-Mannich reaction and in allylation of aldehydes and ketones. These procedures are suitable for one-pot synthesis of alpha-amino acids and homoallyl alcohols from easily available allyl alcohol, amine, aldehyde, or ketone substrates. In the presented transformations, the active allylating agents

  通过在 Petasis borono-Mannich 反应和醛和酮的烯丙基化中整合烯丙醇的钳形复合物催化硼化反应，设计了一种高效的一锅法。这些程序适用于从容易获得的烯丙醇、胺、醛或酮底物一锅法合成 α-氨基酸和高烯丙醇。在所提出的转化中，活性烯丙基化剂是原位生成的烯丙基硼酸衍生物。这些瞬态中间体被证明是对酸、碱、醇、水和空气稳定的物质，它们与各种醛/酮和亚胺亲电子试剂的烯丙基化反应条件具有高度的相容性。反应的硼酸盐来源是二硼酸或原位水解的二硼酸酯，以确保反应的废产物是无毒的硼酸。该反应的区域选择性和立体选择性非常好，因为几乎所有产物都以单一区域和立体异构体形式形成。所描述的程序适用于在支链烯丙基产物中产生季碳中心，而不会形成相应的线性烯丙基异构体。此外，包含三个立体中心的产品作为单一产品形成而没有形成其他非对映异构体。由于高度规范的连续过程，最多可以作为一锅序列选择性地执行四步、四组分转换

  A general and efficient zinc-alkoxide-catalyzed allylation of a diverse array of ketones with allyl boronates is presented. The methodology is effective with 2 mol % of catalyst and with relatively short reaction times. Studies of the key exchange process are presented, which support a cyclic transition state for the boron to zinc exchange.
• Regio- and Stereochemistry on the Electrophilic Trapping of Allylic Samariums Generated by Reductive Cleavage of Allylic Ethers with (C₅Me₅)₂Sm(thf)_<i>n</i>

  The C-O bond of allylic benzyl ethers was selectively cleaved with Cp-2*Sm(thf)(n) to give allylic samarium complexes in good yields. Facility of their bond fission has been found to be comparable to that of the corresponding propargylic ethers intermolecularly, but lower intramolecularly. Regio- and stereochemistry on the electrophilic trapping of the allylic complexes thus generated remarkably depended on the nature of the electrophiles. They reacted with carbonyl compounds exclusively from the most substituted terminus of the allylic moieties to yield blanched homoallylic alcohols with anti diasteroselectivity. On the other hand, trapping with silyl chlorides produced linear allylic silanes. Here, a plausible mechanism to account for the difference is proposed.
