• 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

  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。
• Conjugate Additions of a Simple Monosilylcopper Reagent with Use of the CuI·DMS Complex:  Stereoselectivities and a Dramatic Impact by DMS

  reagent with DMS as the solvent is very useful with sterically hindered (β,β-disubstituted) enones, and provides very high yields of the β-silylated 1,4-addition products. Since there is no oligomerization problem associated with the simple monosilylcuprate reagent, this reagent should be considered as a very useful 1,4-silyl donor to enals, enones, and enoates in conjugate addition reactions.

  描述了利用简单的单甲硅烷基铜酸盐试剂Li [PhMe 2 SiCuI]与α，β-不饱和羰基化合物进行共轭加成。作为（CuI）4（DMS）3配合物的组分或添加的溶剂，二甲基硫醚（DMS）的存在对其化学收率和非对映体比率（dr）的水平都具有惊人的影响。产品。吉尔曼型甲硅烷基氰基甲酸酯Li（Ph 2 MeSi）2 Cu / LiCN}先前已被用来保证在共轭加成反应中获得良好的结果。与简单的Li [PhMe 2]结合使用时，不需要外部添加剂，例如HMPA，三丁基膦或二烷基锌SiCuI]试剂。已经证明，以DMS为溶剂的单甲硅烷基铜酸盐试剂与空间受阻的（β，β-二取代的）烯酮非常有用，并且提供非常高产率的β-甲硅烷基化的1，4-加成产物。由于不存在与简单的单甲硅烷基铜酸酯试剂相关的低聚问题，因此该试剂应被认为是共轭加成反应中烯，烯酮和烯酸酯的非常有用的1,4-甲硅烷基供体。

  Conjugate addition reactions using the simple Li[PhMe2SiCuI] reagent to a variety of α,β-unsaturated carbonyl compounds is described; dimethyl sulfide from the purification of CuI plays a key role for very high yields as well as high stereoselectivities in the formation of β-silyl carbonyl compounds.

  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.
