  Novel and practical preparation of α-fluoro-functionalized esters from fluoroiodoacetates

  摘要：

  The addition reaction of fluoroiodoacetates 2 to various electron-rich alkenes 3 initiated by iron powder in dry THF at 70-80 degrees C gave 1 : 1 adducts 4 in good yields. A variety of functionalities in the alkenes such as trimethylsilyl, alkoxy, acetoxy, hydroxy and ester could be tolerated under the reaction conditions. Reduction of the adducts 4 with Zn-AcOH in ethanol or Zn-NiCl2 . 6H(2)O in moist THF was readily accomplished, and the overall procedure was amenable to a convenient one-flask procedure, Treatment of fluoroiodoacetates 2 with electron-deficient alkenes 7 in the presence of an Fe-CrCl3 . 6H(2)O-bpy bimetal redox system in ethanol at 70-80 degrees C resulted in the formation of iodine-free 1 : 1 adducts 8 in moderate to good yields. It is proposed that the addition reactions of fluoroiodoacetates 2 to electron-rich and electron-deficient alkenes proceeded through a single-electron-transfer mechanism.

  Treatment of the methyl ethers MeOX (X = Me, Ph) with a stoicheiometric amount of bistrifluoromethyl nitroxide [(CF3)2NO·= R·] at room temperature converts them efficiently into their bistrifluoromethylamino-oxymethyl counterparts, RCH2OX; the bis-derivative (RCH2)2O is a minor by-product in the case of dimethyl ether (X = Me). Multiple hydrogen-abstraction increases in importance with diethyl ether

  在室温下用化学计量的双三氟甲基氮氧化物[（CF 3）2 NO·= R·]处理甲基醚MeOX（X = Me，Ph），可将它们有效地转化为双三氟甲基氨基-氧甲基甲基对应物RCH 2 OX；在二甲醚（X = Me）的情况下，双衍生物（RCH 2）2 O是次要的副产物。在重要性多个夺氢增加用二乙醚作为底物，预期产品RCHMeOEt和（RCHMe）2 O为伴随有双-衍生物（RCH 2 CHROEt）可以说是产生经由所述αβ-脱氢2R·+的Et 2 ö → 2RH + CH2个 卤代醚MeOCF 2 CHFCl在50°C下与氮氧化物缓慢反应，生成衍生物RCH 2 OCF 2 CHFCl和RCFClCFCF 2 OMe的7：1混合物，水解后得到酯RCH 2 OCOCHFCl和RCFClCO 2 Me，分别。后者的酯最好通过将氯氟乙酸甲酯与双三氟乙酸酯和双三氟甲基氮氧化物处理来获得。

  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.

  fluoroether were carried out with SbF3 and a catalytic amount of Br2 in SO2Cl2 at room temperature. Bis(2-chloro-2,2-difluoroethyl) difluoroformal and 2-chloro-1,1,2-trifluoroethyl methyl ether were converted to bis(2-chloro-2,2-difluoroethyl) carbonate and methyl chlorofluoroacetate, respectively.

• Electrolytic Reactions of Fluoroorganic Compounds. 14. Regioselective Anodic Methoxylation of N-(Fluoroethyl)amines. Preparation of Highly Useful Fluoroalkylated Building Blocks
  作者：Toshio Fuchigami、Shinji Ichikawa

  DOI：10.1021/jo00082a018

  日期：1994.2

  Anodic methoxylation of various types of N-(fluoroethyl)amines, ArRNCH(2)R(f) (R(f) = CF3, CHF2, CH2F, etc.) has been systematically studied and it was found that a methoxy group was exclusively or preferentially introduced into the position a to the fluoromethyl (R(f)) group, depending on the R(f) and R groups. The effect of the R(f) group on the promotion of the anodic alpha-methoxylation decreased in the order CF3, CHF2, and CH2F. This remarkable promotion effect and unique regioselectivity can be explained mainly in terms of the alpha-CH kinetic acidities of the cation radicals formed by one-electron oxidation of the amines. The alpha-methoxylated products are highly useful precursors for the construction of carbon-carbon bonds alpha to the trifluoromethyl and difluoromethyl groups, which is difficult by other methods.
