  • 2,2-Di(ethoxy)vinyllithium: A synthetic equivalent of the ethyl acetate anion
    作者:Heng-xu Wei、Manfred Schlosser
    DOI:10.1016/0040-4039(96)00416-9
    日期:1996.4
    2,2-Diethoxyvinyllithium can be readily generated from 2-bromo-1,1-diethoxyethylene by treatment with butyllithium. When dissolved in tetrahydrofuran, it can be stored at −25 °C for hours, but decomposes rapidly at 0 °C.
    通过用丁基锂处理,可以容易地从2-溴-1,1-二乙氧基乙烯生成2,2-二乙氧基乙烯基锂。溶于四氢呋喃后,可在-25°C下保存数小时,但在0°C下会迅速分解。
  • 2,2-Di(ethoxy)vinyllithium: Reactions with carbonyl compounds
    作者:Abdelaziz Hiouni、Lucette Duhamel
    DOI:10.1016/0040-4039(96)01163-x
    日期:1996.7
    2,2-Di(ethoxy)vinyllithium 2 generated from bromo ketene acetal 1 reacts with carbonyl compounds to give either β-hydroxy esters 5 or conjugated esters 6 or hydroxy ketene acetals 7 according to the work up.
    由溴乙烯酮缩醛1产生的2,2-二(乙氧基)乙烯基锂2与羰基化合物反应,根据后处理得到β-羟基酯5或共轭酯6或羟基烯酮缩醛7。
  • Divergent Synthesis of Natural Derivatives of (+)‐Saxitoxin Including 11‐Saxitoxinethanoic Acid
    作者:James R. Walker、Jeffrey E. Merit、Rhiannon Thomas‐Tran、Doris T. Y. Tang、J. Du Bois
    DOI:10.1002/anie.201811717
    日期:2019.2.4
    The bis-guanidinium toxins are a collection of natural products that display nanomolar potency against select isoforms of eukaryotic voltage-gated Na+ ion channels. We describe a synthetic strategy that enables access to four of these poisons, namely 11-saxitoxinethanoic acid, C13-acetoxy saxitoxin, decarbamoyl saxitoxin, and saxitoxin. Highlights of this work include an unusual Mislow-Evans rearrangement
    双胍盐毒素是天然产物的集合,这些天然产物对真核电压门控Na +离子通道的某些同工型具有纳摩尔效价。我们描述了一种合成策略,该策略能够获取其中四种毒物,即11-萨克毒素毒素,C13-乙酰氧基毒素,十氨基甲酰基毒素和毒素。这项工作的重点包括异常的Mislow-Evans重排和后期的Stille乙烯酮缩醛偶联。相对于大鼠NaV 1.4测量了11-萨克斯毒素乙基酸的IC50值,发现其为17.0 nm,类似于硫酸毒素gonyautoxin II和III的IC50值。
  • 2-Ethoxyvinyllithiums and diethoxyvinyllithiums : what makes them stable or fragile?
    作者:Manfred Schlosser、Heng-xu Wei
    DOI:10.1016/s0040-4020(96)01075-7
    日期:1997.2
    The elusive (E)-2-ethoxyvinyllithium can be readily generated in tetrahydrofuran at -75 degrees C from (E)-1-bromo-2-ethoxyethylene by halogen/metal exchange and subsequently trapped with electrophiles. Alkylation opens a convenient entry to (E)-configurated enethers. (E)-2-Ethoxyvinyllithium decomposes rapidly at -50 degrees C whereas its (Z)-isomer, which lacks the possibility to eliminate lithium ethoxide in a favorable anti-periplanar process, is stable under the same conditions. (E)-1,2-Diethoxyvinyllithium even sustains reflux temperatures (approximately 75 degrees C). 2,2-Diethoxyvinyllithium and (Z)-1,2-diethoxyvinyllithium can be conserved at 0 degrees C although this time loss of alcoholate can occur in the anti-mode. Obviously it matters whether the energy-rich ethoxyacetylene is formed as the elimination product or simple acetylene, as in the case of (E)-2-ethoxyvinyllithium. (C) 1997, Elsevier Science Ltd.
