  • A new route to α-trifluoromethyl-α,β-unsaturated esters
    作者:Xingang Zhang、Feng-Ling Qing、Yonggang Yang、Jiang Yu、Xiang-Kai Fu
    DOI:10.1016/s0040-4039(00)00279-3
    日期:2000.4
    The treatment of α-bromo-α,β-unsaturated esters with FSO2CF2CO2Me and CuI in DMF/HMPA constitutes a new synthetic scheme for the preparation of α-trifluoromethyl-α,β-unsaturated esters.
    DMF / HMPA中用FSO 2 CF 2 CO 2 Me和CuI处理α--α,β-不饱和酯构成了制备α-三甲基-α,β-不饱和酯的新合成方案。
  • Synthesis of 2‘,3‘-Dideoxy-2‘-trifluoromethylnucleosides from α-Trifluoromethyl-α,β-unsaturated Ester
    作者:Xingang Zhang、Feng-Ling Qing、Yihua Yu
    DOI:10.1021/jo005520r
    日期:2000.10.1
    beta-unsaturated esters 3. The trifluoromethylation of (Z)/(E)-ethyl 3-[(S)-2,2-dimethyl-1,3-dioxolan-4-yl]-2-bromo-2-propenoate (2e), which is derived from 1-(R)-glyceraldehyde acetonide, yields the key intermediate alpha-trifluoromethyl-alpha,beta-unsaturated esters 3e. This is transformed into anomeric acetates 8a and 8b and is used for the synthesis of a number of 2', 3'-dideoxy-2'-trifluoromethylnucleosides

  • Diastereoselective Thia-Claisen Rearrangement of Pyrrolidinone-Derived Ketene<i>N</i>,<i>S</i>-Acetals
    作者:Michael Porter、Adam Ellwood、Anne Mortimer、Derek Tocher
    DOI:10.1055/s-2008-1078030
    日期:2008.8
    Thia-Claisen rearrangements of S-allylic ketene N,S-­acetals were carried out using substrates with an external allylic stereogenic centre. High levels of diastereoselectivity were observed only when a bromine substituent was introduced onto the double bond.
    使用带有外部烯丙基手性中心的底物进行了S-烯丙基烯酮N,S-乙缩醛的Thia-Claisen重排反应,仅当双键上引入取代基时,才观察到高平的非对映选择性。

    作者:Klaus Jähnisch
    DOI:10.1002/jlac.199719970419
    日期:1997.4
    Enantiomerically pure cis- and trans-1H-aziridine-carboxylic acid derivatives 2a, b and 3a, b have been prepared by asymmetric Michael-type addition of ammonia to chiral acrylates 1a, b with high syn selectivity. The title compounds were obtained from the diols 8a, b by Corey-Winter olefination.

  • Reversal of facial selectivity in a thia-Claisen rearrangement by incorporation of a vinylic bromine substituent
    作者:Adam R. Ellwood、Anne J. Price Mortimer、Jonathan M. Goodman、Michael J. Porter
    DOI:10.1039/c3ob41580e
    日期:——
    Thia-Claisen rearrangements have been carried out using N-benzylpyrrolidine-2-thione and chiral allylic bromides derived from D-mannitol. Introduction of a bromine atom onto the double bond of the allylic bromide reverses the sense of diastereoselectivity in the [3,3]-sigmatropic rearrangement. Density functional theory calculations lead us to rationalise the observed selectivity in terms of a Cíeplak
    使用N-苄基吡咯烷-2-酮和衍生自D-甘露糖醇的手性烯丙基化物进行了Thia-Claisen重排。将溴原子引入烯丙基的双键上可以逆转[3,3]-σ重排中的非对映选择性。密度泛函理论计算使我们根据塞普拉克效应合理化了观察到的选择性。
