  • α-Trifluoromethylation of Secondary and Sterically Hindered Carboxylates with Use of BrF<sub>3</sub>
    作者:Aviv Hagooly、Shlomo Rozen
    DOI:10.1021/jo048864g
    日期:2004.10.1
    Secondary esters and those with sterical hindrance at the beta carbon were reacted with base, carbon disulfide, and methyl iodide to produce methyl 2-carboalkoxydithioalkenoate (2). These compounds were reacted with BrF3, forming the corresponding alpha-trifluoromethyl esters (3) along with 1,1-difluoro-2-trifluoromethyl-2-alkyl ethers (4). The products of type 4 have been transformed to derivatives of type 3, thus raising the overall yields of the target respective cc-trifluoromethyl esters to 65-80%. The reaction is tolerant to different functional groups such as halogens, protected alcohols, esters, and lactones.
  • Lewis Acid Catalyzed Synthesis of α-Trifluoromethyl Esters and Lactones by Electrophilic Trifluoromethylation
    作者:Dmitry Katayev、Václav Matoušek、Raffael Koller、Antonio Togni
    DOI:10.1021/acs.orglett.5b03088
    日期:2015.12.4
    An electrophilic trifluoromethylation of ketene silyl acetals (KSAs) by hypervalent iodine reagents 1 and 2 has been developed. The reaction proceeds under very mild conditions in the presence of a catalytic amount of trimethylsilyl bis(trifluoromethanesulfonyl)imide (up to 2.5 mol %) as a Lewis acid providing a direct access to a variety of secondary, tertiary, and quaternary α-trifluoromethyl esters
    已经开发了由高价碘试剂1和2进行的乙烯酮甲硅烷基缩醛(KSAs)的亲电子三氟甲基化反应。反应在非常温和的条件下,在催化量的三甲基甲硅烷基双(三氟甲磺酰基)酰亚胺(至多2.5 mol%)的路易斯酸存在下进行,可直接获得各种仲,叔和季α-三氟甲基酯和内酯,收率高(高达98%)。
