    γ-dimethylallyl magnesium bromides) and secondary alkyl [s-butyl magnesium bromide and (1,2-dimethylpropyl) magnesium chloride] Grignard reagents to form pairs of diastereoisomeric alcohols R′—CHMeCHOH—R (R′ = CH2CH, CH2CMe, Et and iPr, respectively). The reactions involving the secondary alkyl Grignard reagents are not stereoselective; those involving the allylic Grignard reagents show some stereoselectivity

    to produce unisolable allylchromium species which add efficiently to aldehydes or ketones with high degree of stereo- and chemoselectivity. Particularly, high threo selectivity is observed in the reaction of aldehydes and 1-bromo-2-butene and is ascribed to a chair-like six-membered transition state. Simple reduction of allylic and benzylic halides produces biallyls and bibenzyls, while gem-dibromocyclopropanes
    低价铬试剂由氯化铬 (III) 和半摩尔氢化铝锂在四氢呋喃中生成。该试剂的行为类似于市售的无水氯化铬 (II),并还原烯丙基卤化物以产生不可溶的烯丙基铬物质,该物质可有效地添加到醛或酮中,具有高度的立体选择性和化学选择性。特别是,在醛和 1-溴-2-丁烯的反应中观察到高苏选择性,这归因于椅子状六元过渡态。烯丙基和苄基卤化物的简单还原产生二烯丙基和联苄基,而偕二溴环丙烷以优异的产率提供相应的丙二烯。

  • Total synthesis of milbemycin E: synthesis of the C(11)–C(25) fragment
    作者:Patrick G. Steel、Eric J. Thomas
    DOI:10.1039/a605892b
    日期:——
    Treatment of 2-methylpropanal with the (E)-but-2-enyl(diisopinocampheyl)borane 9 prepared from (+)-α-pinene gives the anti- and syn-products 10 and 11, ratio 88∶12, from which the major anti-isomer 10 is separated by preparative GLC. Hydroboration–oxidation of its tert-butyldimethylsilyl ether 14 gives the primary alcohol 15 which has been converted into the bromide 16 and iodide 17. The propenyl(diisopinocampheyl)borane 23 prepared from (-)-α-pinene reacts with the aldehyde 22 prepared from (S)-malic acid to give the anti- and syn-1,3-diol derivatives 24 and 25, ratio 86∶14, and the anti-product 24 has been taken through to the epoxide 31. Sequential alkylation of 1,3-dithiane with the iodide 17 and the epoxide 31 gives the 2,2-dialkyl-1,3-dithiane 33 which is converted into the spiroacetal 4 by treatment with dilute aqueous hydrogen fluoride. After protection, ozonolysis gives the aldehyde 43 which has been condensed with the ylide 34 to give the α,β-unsaturated ester 44. This has been reduced and converted into the iodide 46 which has been used to alkylate the chiral oxazolidinone 39 to give the required C(11)–C(25) fragment 48 of milbemycin E 1 after reductive removal of the chiral auxiliary. This has been converted into the phosphonium salt 2 ready for Wittig coupling with the hydroxybutenolide 3 for the assembly of the milbemycin nucleus.

  • Stereo- and regiocontrol of acyclic systems via the lewis acid mediated reaction of allylic stannanes with aldehydes
    作者:Yoshinori Yamamoto、Hidetaka Yatagai、Yuji Ishihara、Norihiko Maeda、Kazuhiro Maruyama

    日期:1984.1
    The reaction of crotyltrialkylstannanes (1) with aldehydes in the presence of BF3,OEt2, produces the corresponding erythro homoallyl alcohols (2) predominantly regardless of the geometry of the double bond. Further, the Lewis acid mediated reaction exhibits the enhanced Cram selectivity in comparison with other allylic organometallic reactions which proceed in the absence of Lewis acids. Use of AlCl3-i-PrOH
    在BF 3,OEt 2存在下,巴豆基三烷基锡烷(1)与醛的反应主要产生相应的赤型均烯丙基醇(2),而与双键的几何形状无关。此外,与在不存在路易斯酸的情况下进行的其他烯丙基有机金属反应相比,路易斯酸介导的反应显示出提高的Cram选择性。使用AlCl 3 -i-PrOH作为路易斯酸完全改变了反应过程;产生线性加合物(12)而不是支链加合物(13)。1-BF 3,OEt 2的反应该系统被用于(±)Prelog-Djerassi乳酸(16)和(-)芦竹内酯(19)的短时和立体选择性合成。
