    摘要:
    (salen)Al 催化的水杨醛肟与 α,β-不饱和酰亚胺的不对称共轭加成是这些缺电子烯烃高效且高度对映选择性的两步形式水合的关键步骤。该反应构成了以氧为中心的亲核试剂与 α,β-不饱和羧酸衍生物的对映选择性共轭加成的第一个例子。将该方法应用于手性非外消旋底物显示出高水平的催化剂诱导的非对映选择性,强调了其在聚酮化合物天然产物合成中的潜在用途。

  • Approaches toward the Total Synthesis of the Nine-Membered Thio-Lactone Core of Griseoviridin
    作者:Xavier Moreau、Jean-Marc Campagne
    DOI:10.1021/jo034195f
    日期:2003.6.1
    toward the synthesis of the macrocyclic thiolactone core of griseoviridin have been studied. Intramolecular palladium-catalyzed thiol coupling and esterification (carboxylate activation) have led to the formation of unexpected rearranged products. An intermolecular palladium-catalyzed thiol/vinyl iodide coupling followed by an esterification (alcohol activation) ultimately led to the nine-membered

  • Allylic organometallic way to control acyclic stereochemistry and its application to the synthesis of carbohydrates
    作者:Yoshinori Yamamoto、Toshiaki Komatsu、Kazuhiro Maruyama
    DOI:10.1016/0022-328x(85)87354-x
    日期:1985.4
    The Cram/anti-Cram selectivity in the reactions of allylmetals with aldehydes and the erythro/threo selectivity in the reactions of substituted allylic organometallic compounds with other aldehydes can be controlled by the metal (M). Based on both selectivities, we can predict the diastereofacial selectivity of more complex systems. Finally, 1-O-methyl-2,6-dideoxyhexose and 1-O,3-O-dimethyl-4,6-dideoxyhexose
    烯丙基金属与醛的反应中的Cram / anti-Cram选择性和取代的烯丙基有机金属化合物与其他醛的反应中的赤/苏选择性可以通过金属(M)控制。基于这两种选择性,我们可以预测更复杂系统的非对面选择性。最后,制备1-O-甲基-2,6-二脱氧己糖和1-O,3-O-二甲基-4,6-二脱氧己糖。
  • Substrate-controlled stereoselectivity in the Yamamoto aldol reaction
    作者:Nadin Schläger、Andreas Kirschning
    DOI:10.1039/c2ob26185e
    日期:——
    The Yamamoto aldol reaction is a vinylogous aldol reaction that relies on bulky aluminium-based Lewis acids. These activate both the aldehyde as well as become part of the enolate moiety. The report discloses the first detailed study on the substrate-controlled Yamamoto aldol reaction in which 2,3-syn and 2,3-anti disubstituted aldehydes serve as the stereodirecting elements. The “size” of the substituent in the β-position strongly determines the facial selectivity of enolate addition to the aldehyde. Large substituents favour formation of 1,3-syn diols while slim alkynyl groups preferentially lead to 1,3-anti products.
    山本 aldol 反应是一种依赖于笨态铝基路易斯酸的传统 aldol 反应。这些路易斯酸不仅激活醛,还成为烯醇负离子部分的一部分。该报告首次详细研究了底物控制的山本 aldol 反应,其中 2,3-syn 和 2,3-anti 二取代醛作为立体导向元素。β-位取代基的“大小”强烈决定了烯醇添加至醛的面选择性。大的取代基有利于形成 1,3-syn 二醇,而纤细的炔基团则优先生成 1,3-anti 产品。
  • Synthetic Studies on Oligomycins. Synthesis of the Oligomycin B Spiroketal and Polypropionate Portions
    作者:Masaya Nakata、Takashi Ishiyama、Shinichi Akamatsu、Youichi Hirose、Hiroshi Maruoka、Rika Suzuki、Kuniaki Tatsuta
    DOI:10.1246/bcsj.68.967
    日期:1995.3
    The oligomycin B spiroketal portion, [2S,2(2R),3S,6R,8S,8(3R),9S,10R,11S]-2-[2-(t-butyldiphenylsilyloxy)propyl]-8-[3-(hydroxymethyl)pentyl]-3,9,11-trimethyl-1,7-dioxaspiro[5.5]undecane-5,10-diol (2), and polypropionate portion, ethyl (2E,4S,5R,6R,7S,8S,9R,10S,12R,13S,14R,16E)-5-(t-butyldimethylsilyloxy)7,9-(isopropylidenedioxy)-12,13-(4-methoxybenzylidenedioxy)-4,6,8,10,12,14-hexamethyl-11-oxo-18-phenylsulfonyloctadeca-2,16-dienoate (3), have been synthesized. The C19-C21 Wittig salt, [(2S,3R)-2-ethyl-3,4-(isopropylidenedioxy)butyl]triphenylphosphonium iodide (6), prepared from 2-butene-1,4-diol via Sharpless epoxidation, was coupled with the C22-C27 aldehyde, benzyl 2,4-dideoxy-3-O-(4-methoxybenzyl)-2,4-di-C-methyl-α,β-l-galacto-hexodialdopyranoside-(1,5) (7), prepared from (Z)-2-butene-1,4-diol via Sharpless epoxidation and the Brown’s crotylboration. The resulting coupling product was transformed to the C19-C27 lactone, [3S,4R,5R,6S,6(3R,4R)]-6-[3-ethyl-4,5-(isopropylidenedioxy)pentyl]-4-(4-methoxybenzyloxy)-3,5-dimethyl-3,4,5,6-tetrahydro-2H-pyran-2-one (4). The C28-C34 organostannane compound, (2R,4S,5S,7RS)-2-(t-butyldiphenylsilyloxy)-5-methyl-7-(tributylstannyl)-4-(triethylsilyloxy)-7-[(2-trimethylsilylethoxy)methoxy]heptane (5b), was prepared from (R)-methyl 3-hydroxybutyrate via the Brown’s crotylboration and the Still’s stannylation. After lithiation of 5b with butyllithium, the resulting α-alkoxy organolithium compound was coupled with 4 and the product was converted to the C19-C34 spiroketal, [2S,2(2R),3S,6R,8S,8(3R,4R),9S,10R,11S]-2-[2-(t-butyldiphenylsilyloxy)propyl]-8-[3-ethyl-4,5-(isopropylidenedioxy)pentyl]-10-(4-methoxybenzyloxy)-3,9,11-trimethyl-1,7-dioxaspiro[5.5]undecan-5-ol (37). The synthetic 2, derived from 37, was identical to the oligomycins (A, B, C mixture) degradation product in all respects, which elucidates the absolute stereochemistry of oligomycin B (1b). The C3-C9 aldehyde, (2-trimethylsilylethoxy)methyl 2,4,6-trideoxy-3-O-(4-methoxybenzyl)-2,4,6-tri-C-methyl-d-glycero-α-l-ido-heptodialdopyranoside-(1,5) (9), was prepared from (2S)-3-(t-butyldimethylsilyloxy)-2-methylpropanal via Keck’s crotylstannane addition and Brown’s crotylboration. The aldol coupling between the zinc enolate of the C10-C16 ketone, t-butyldimethylsilyl 2,3,7,8-tetradeoxy-4-O-(4-methoxybenzyl)-3,5-di-C-methyl-α-l-xylo-octopyranosid-6-ulose (10), prepared from methyl (R)-(+)-lactate via Brown’s crotylboration and a metallated methoxyallene addition, and aldehyde 9 gave the C8-C9 syn, C9-C10 syn product, which was transformed to the oligomycin B polypropionate portion 3 through elongation of the C1-C2 and C17-C18 carbon units.
