    摘要:
    有机锂、格氏试剂和硼氢化还原剂攻击2-酰基-1-萘酰胺,以高或完全的鞘旋选择性生成三级和二级醇。在从相同酮衍生的烯醇盐的烷基化反应中,也可以获得高水平的立体选择性,尽管产物酮的热消旋化低能障碍使得烷基化的动力学立体选择性难以准确测定。在这两种情况下,攻击的方向受到芳香酰胺取代基的垂直构象控制,其NR2基团遮蔽了酮的一侧。

  • Atroposelective attack of nucleophiles on 2-formyl-1-naphthamides and their derivatives: chelation and non-chelation control
    作者:Jonathan Clayden、Catherine McCarthy、Neil Westlund、Christopher S. Frampton
    DOI:10.1039/b000669f
    日期:——
    Organometallic nucleophiles attack 2-formyl-1-naphthamides to give secondary alcohols with widely varying atroposelectivity. By careful choice of reagent, selectivities of up to >99∶1 in favour of either the anti or the syn atropisomer can be obtained. Ethers and amines may be synthesised atroposelectively from acetals or imines. The sense of the selectivity is determined by the reactive conformation of the Ar–CHO bond, itself dependent on the coordinating and chelating ability of the nucleophile’s counterion. The roles of conformation, Lewis acids, and chelation/non-chelation control in relation to stereoselectivity are discussed.
    有机金属核苷类物质攻击2-芳醛-1-萘酰胺,生成具有广泛变异的次级醇的非对映选择性。通过仔细选择试剂,可以获得高达99:1的选择性,偏向于反式或顺式对映异构体。醚类和胺类可以从缩醛或亚胺中选择性合成。选择性的方向由Ar–CHO键的反应构象决定,而这又依赖于核苷的配对离子的配位和螯合能力。文中讨论了构象、路易斯酸和螯合/非螯合控制与立体选择性之间的关系。

    dialkylzinc reagents add to atropisomeric 2-formyl arylamides many times faster than they react with other substituted benzaldehyde derivatives. Additionally, with diethylzinc the products were formed with very high diastereoselectivity, affording the syn product (d.r. greater than 95:5), except in one case where epimerization of the product is rapid. In contrast, Grignard and trialkylaluminum reagents afforded

  • Atroposelectivity in the electrophilic substitution reactions of laterally lithiated and silylated tertiary amides
    作者:Jonathan Clayden、Jennifer H. Pink、Neil Westlund、Christopher S. Frampton
    DOI:10.1039/b200358a
    日期:2002.3.25
    Lateral lithiation–electrophilic quench of 2-alkyl-1-naphthamides and 2,6-dialkylbenzamides yields products containing an atropisomeric Ar–CO axis and a new stereogenic centre with high (generally >95 ∶ 5) diastereoselectivity. With imines as electrophiles, single diastereoisomers containing an atropisomeric axis and two new stereogenic centres are formed. 2,6-Dialkylbenzamides may be functionalised stereoselectively at both the 2- and 6-positions, leading (with imines) to symmetrical compounds bearing 1,7-related stereogenic centres. 2-Alkylbenzamides with only one ortho alkyl group are not atropisomeric at ambient temperature but are functionalised diastereoselectively by lateral lithiation–electrophilic quench at −78 °C. Stabilisation of the atropisomeric products by further lithiation and alkylation proves their diastereoselective formation. The lack of stereospecificity in the fluoride-promoted reaction of a laterally silylated 1-naphthamide with an aldehyde suggests that reported reactions of laterally silylated benzamides may also be controlled by the rotationally restricted amide group.

  • Atroposelective attack of nucleophiles and electrophiles on 2-acyl-1-naphthamides and their enolates
    作者:Jonathan Clayden、Neil Westlund、Roy L. Beddoes、Madeleine Helliwell
    DOI:10.1039/b000668h
    日期:——
    Organolithiums, Grignard reagents and borohydride reducing agents attack 2-acyl-1-naphthamides to give tertiary and secondary alcohols with high or complete atroposelectivity. High levels of stereoselectivity can also be obtained in the alkylations of enolates derived from the same ketones, though the low barrier to thermal epimerisation of the product ketones prevents accurate determination of the kinetic stereoselectivity of the alkylation. The direction of attack in both cases is controlled by the perpendicular conformation of the aromatic amide substituent, whose NR2 group shields one face of the ketone.
