  • Ethyl phenylsulfinyl fluoroacetate, a new and versatile reagent for the preparation of α-fluoro-α,β-unsaturated carboxylic acid esters
    作者:Thomas Allmendinger
    DOI:10.1016/s0040-4020(01)80956-x
    日期:1991.1
    The title compound 2 can be alkylated with a wide range of alkyl halides and Michael acceptors. Subsequent thermal elimination of phenyl sulfinic acid 3 leads to α-fluoro-α,β-unsaturated ethyl carboxylates 5 and 10, an important class of intermediates for fluorine containing biologically active compounds.

  • A Novel Intramolecular Horner-Wadsworth-Emmons Reaction: A Simple and General Route to .alpha.-Fluoro-.alpha.,.beta.-unsaturated Diesters
    作者:Hou-Jen Tsai、Alagappan Thenappan、Donald J. Burton
    DOI:10.1021/jo00102a038
    日期:1994.11
    Diethyl (fluorocarbethoxymethyl)phosphonate (1), prepared from triethyl phosphite and ethyl bbromofluoroacetate, reacts with n-butyllithium in THF to give the phosphonate carbanion 2. Addition of the pregenerated carbanion 2 to a THF solution of methyl or ethyl oxalyl chloride at -78 degrees C forms the acylated phosphonate (EtO)(2)P(O)CF(COCO(2)R)CO(2)Et (3). In situ reaction of 3 with Grignard reagents affords alpha-fluoro-alpha,beta-unsaturated diesters R'(CO(2)R)C=CFCO(2)Et in moderate to good yields with high E-stereoselectivity. The reaction is applicable to primary, secondary, and tertiary alkyl, alkenyl, alkynyl, aryl, cyclohexyl, and perfluorinated Grignard reagents. The assignment of E and Z configuration is based on NOE experiment. The E/Z ratio of unsaturated diesters formed in the reaction varies with the metal ion and cosolvent. However, solvents and bases have little influence on the stereoselectivity.
  • Isolation and Characterization of intermediate in the Synthesis of α-Fluorodiesters
    作者:Hou-Jen Tsai
    DOI:10.1002/jccs.199800082
    日期:1998.8
    AbstractThe anion [(EtO)2P(O)CFCO2Et]Li+, pregenerated from its precursor diethyl (carboethoxyfluoromethyl)phosphonate (EtO)2P(O)CFHCO2Et and n‐butyllithium, was added via syringe to a THF solution of ethyl oxaiyl chloride to yield an acylated phosphonate (EtO)2P(O)CF(COCO2Et)CO2Et. In situ reaction with Grignard reagents RMgX produces the α‐fluorodiesters (E,Z)‐R(CO2Et)C=CFCO2Et in good yields. In contrast, addition of ethyl oxalyl chloride to a THF solution of diethyl (carboethoxyfluoromethyl)phosphonate anion gives an isolated intermediate (EtO)2P(O)CFCO2Et(CO2Et)C=CFCO2Et. Subsequent reaction of this isolated intermediate with Grignard reagents also affords a one‐pot synthesis of the α‐fluorodiesters with high E‐stereoselectivity. The E‐stereoselectivity increases when HMPT or DMPU is used as a cosolvent in the preparation of diethyl 2‐fluoro‐3‐phenylfumarate (E,Z)‐Ph(CO2Et)C=CFCO2Et.
