  • Reactivity and Enantioselectivity in the Reactions of Scalemic Stereogenic α-(<i>N</i>-Carbamoyl)alkylcuprates

    ine and THF soluble CuCN·2LiCl react with vinyl iodides, vinyl triflates, β-iodo-α,β-enoates, propargyl mesylates, and allyl bromide to afford the substitution products with excellent enantioselectivity. Excellent enantiomeric ratios are obtained in the conjugate addition reactions with methyl vinyl ketone while low enantiomeric ratios can be achieved with acrylate esters using HMPA/TMSCl activation

  • Lead Tetraacetate Induced Addition Reaction of Difluorodiiodomethane to Alkenes and Alkynes. Synthesis of Fluorinated Telechelic Compounds

    Lead tetraacetate (LTA) can smoothly induce the addition reaction of difluorodiiodomethane (1) with electron-rich alkenes at 60°C in diglyme to give monoadducts (RCHICH2CF2I) and diadducts (RCHICH2)2. The similar, clean reaction of fluoroolefins, such as tetrafluoroethene, hexafluoropropene, with 1 occurs only in acetic acid. However, non-fluorinated β-iodo-α,β-unsaturated carboxylic esters are obtained when 1 reacts with alkynes in alcohol. The iododifluoromethyl radical generated by possible pathways from 1 with LTA is discussed.
    在 60°C 的二甘醇中,四乙酸铅(LTA)可以顺利地诱导二二碘甲烷(1)与富电子烯烃发生加成反应,生成单加成物(RCHICH2CF2I)和二加成物(RCHICH2)2。烯烃(如四氟乙烯六氟丙烯)与 1 的类似清洁反应只发生在乙酸中。然而,当 1 与炔烃在醇中反应时,会得到非化的 δ--δ±,δ-不饱和羧酸酯。本文讨论了 1 与 LTA 通过可能的途径生成的氟甲基自由基
  • Copper-Mediated Fluoroalkylation Reactions with Iododifluoroacetamides: Controlling the Selectivity among Cross-Coupling, Intramolecular Cyclization, and Homocoupling Reactions

    Cu-mediated fluoroalkylation reactions with iododifluoroacetamides I have been systematically investigated. It was found that three types of reactions may coexist in Cu-mediated reactions between iododifluoroacetamides and aryl/alkenyl iodides: cross-coupling, intramolecular cyclization, and homocoupling reactions. The selectivity among these three types of reactions could be controlled by tuning the substituents on the nitrogen atom of iododifluoroacetamides, and/or by removing the cross-coupling reaction partner (aryl/alkenyl halides). The general rule is as follows: (a) in the presence of proper aryl/alkenyl iodides, the cross-coupling products 2 (or 6) are generally formed as the major products; (b) in the absence of aryl/alkenyl iodides, and when R-1 = alkyl and R-2 = aryl groups, or when R-1 = R-2 = aryl groups, the intramolecular cyclization products 3 can be formed predominantly; and (c) in the absence of aryl/alkenyl iodides, and when R-1 = R-2 = alkyl groups, or when R-1 = H and R-2 = alkyl, aryl groups, the homocoupling products 4 can be formed dominantly. Our experimental results also indicate that in many cases when cross-coupling, homocoupling, and intramolecular cyclization reactions coexist in the Cu-mediated reaction system, the reactivity decreases in the following order: cross-coupling > intramolecular cyclization > homocoupling.
