  • Copper-Catalyzed Conjugate Addition of a Bis(triorganosilyl) Zinc and a Methyl(triorganosilyl) Magnesium
    作者:Martin Oestreich、Barbara Weiner
    DOI:10.1055/s-2004-831331
    日期:——
    A practical copper-catalyzed conjugate silylation of α,β-unsaturated carbonyl compounds 4 utilizing bis(triorganosilyl) zinc reagent 3 is described. Moreover, mixed methyl(triorganosilyl) magnesium 7 also transfers its silyl ligand to simple enones 4 under copper catalysis.

  • The conjugate addition of a silyl group to enones and its removal with copper(<scp>II</scp>) bromide: a protecting group for the αβ-unsaturation of αβ-unsaturated ketones
    作者:David J. Ager、Ian Fleming、Shailesh K. Patel
    DOI:10.1039/p19810002520
    日期:——
    copper(I) salts react with enones, including esters and aldehydes, to give β-silyl carbonyl compounds in good yield. The β-silylketones can be used in synthesis without risk to the silyl group and the enone group can be restored by bromination-desilylbromination with copper(II) bromide. The principle is illustrated with syntheses of carvone and dihydrojasmone.
    与铜(I)盐混合的甲硅烷基锂试剂与烯酮(包括酯和醛)反应,以高收率得到β-甲硅烷基羰基化合物。β-甲硅烷基酮可用于合成而没有甲硅烷基基团的风险,并且烯酮基团可通过用溴化铜(II)进行溴化-脱甲硅烷基溴化来恢复。香芹酮和二氢茉莉酮的合成说明了该原理。

    cinnamates and β-silyl acrylates by a regiospecific reductive C-silylation using Mg/silyl chloride/DMF system at room temperature. These reductive C-silylation conditions have also been applied to δ-aryl substituted dienoates wherein silylation took place at the δ-position leading to the synthesis of single regioisomeric allylsilanes with very high stereoselectivity.

  • In search of open-chain 1,3-stereocontrol
    作者:Asun Barbero、David C. Blakemore、Ian Fleming、Robert N. Wesley
    DOI:10.1039/a607545b
    日期:——
    Methylation of methyl 4-phenylpentanoate 25 gives the diastereoisomers methyl (2RS,4SR )-2-methyl-4-phenylpentanoate 26 and methyl (2RS,4RS)- 2-methyl-4-phenylpentanoate 27 in a ratio of 44∶56. The aldehydes 3-dimethyl(phenyl)silylbutanal 28, 3-dimethyl(phenyl)silyl-3-phenylpropanal 32 and 3-dimethyl(phenyl)silyl-4-methylpentanal 36, each of which has a stereogenic centre on C-3 carrying a silyl group and successively also a methyl, a phenyl and an isopropyl group, react with a range of methyl, phenyl and isopropyl nucleophiles to give pairs of diastereoisomeric secondary alcohols 40–42, 47–49 and 54–56 having 1,3 related stereocentres. The same alcohols 43–45, 50–52 and 57–59 are also prepared by reduction of the corresponding ketones 29–31, 33–35 and 37–39 with a range of hydride reagents, and three of the ketones, 31, 35 and 39, react with phenyllithium to give mixtures of the tertiary alcohols 46, 53 and 60. The (E)- and (Z)-α,β-unsaturated methyl esters, 61, 62, 64, 65, 67 and 68, prepared from the same three aldehydes with methoxycarbonylmethyltriphenylphosphorane, react with the phenyldimethylsilyl-cuprate and -zincate reagents to give diastereoisomeric pairs of 1,3-disilylated esters. Likewise, the α,β-unsaturated dimethyl diesters, 63, 66 and 69, prepared from the same three aldehydes with dimethyl malonate, react with phenyldimethylsilyllithium and the corresponding cuprate and zincate reagents to give diastereoisomeric pairs of 1,3-disilylated diesters, and with various methyl and phenyl nucleophiles to give the corresponding pairs of diastereoisomeric diesters with stereogenic centres at C-3 and C-5. The relative stereochemistry of all but two of the products having 1,3-related stereocentres has been proved by silyl-to-hydroxy conversion using mercuric acetate and peracetic acid to give the corresponding alcohols or their derived lactones.An attempt to identify a purely steric rule by which it might be possible to predict which diastereoisomer would be the major product in each of these reactions was based on arguments about, and molecular mechanics calculations of, the lowest-energy conformations of the starting materials. The only rule that emerges is that ketones are regularly attacked in sense B, defined in the drawings 21 and 23, in a conformation that minimises the interaction between the group M on the stereogenic centre and the group R1 on the other side of the ketone, but even within this group of reactions, phenyl groups in either or both locations sometimes lead to anomalies.Krapcho reactions take place more rapidly and in higher yield using four equivalents of lithium chloride in place of the usual sodium chloride, and adding two equivalents of water to the DMSO.
    将 4-苯基戊酸甲酯 25 甲酯化,得到非对映异构体(2RS,4SR )-2-甲基-4-苯基戊酸甲酯 26 和(2RS,4RS)-2-甲基-4-苯基戊酸甲酯 27,比例为 44∶56。3-二甲基(苯基)硅基丁醛 28、3-二甲基(苯基)硅基-3-苯基丙醛 32 和 3-二甲基(苯基)硅基-4-甲基戊醛 36,每种醛的 C-3 上都有一个带有硅基的立体中心,并先后带有一个甲基、一个苯基和一个异丙基、与一系列的甲基、苯基和异丙基亲核物反应,得到一对非对映异构的仲醇 40-42、47-49 和 54-56,它们具有 1,3 个相关的立体中心。同样的醇 43-45、50-52 和 57-59 也可以通过相应的酮 29-31、33-35 和 37-39 与一系列氢化物试剂发生还原反应来制备,其中三个酮 31、35 和 39 与苯基锂发生反应,得到叔醇 46、53 和 60 的混合物。 (E)-和(Z)-α,β-不饱和甲基酯 61、62、64、65、67 和 68 由相同的三种醛与甲氧羰基甲基三苯基膦制备而成,它们与苯基二甲基硅琥珀酸酯试剂和锌酸试剂反应,得到非对映异构的 1,3-二硅烷化酯对。同样,由相同的三种醛与丙二酸二甲酯制备的 α、β-不饱和二甲基二酯 63、66 和 69 与苯基二甲基硅烷基锂及相应的铜酸盐和锌酸盐试剂发生反应,生成一对非对映异构的 1,3-二硅烷基二酯,与各种甲基和苯基亲核剂发生反应,生成相应的一对非对映异构的二酯,其立体中心位于 C-3 和 C-5。除了两种具有 1,3 相关立体中心的产物外,其他所有产物的相对立体化学性质都已通过使用乙酸巯基和过乙酸进行硅基-羟基转换而得到相应的醇或其衍生内酯得到证实。出现的唯一规则是,酮在图 21 和图 23 中定义的 B 意义上经常被攻击,其构象使立体中心上的基团 M 与酮另一侧的基团 R1 之间的相互作用最小,但即使在这组反应中,苯基在任一位置或两个位置有时也会导致异常。
