    Oxidative Umpolung α-Alkylation of Ketones
    摘要:
    We disclose a hypervalent iodine mediated α-alkylative umpolung reaction of carbonyl compounds with dialkylzinc as the alkyl source. The reaction is applicable to all common classes of ketones including 1,3-dicarbonyl compounds and regular ketones via their lithium enolates. The α-alkylated carbonyl products are formed in up to 93% yield. An ionic mechanism is inferred based on meticulous analysis, NMR studies, trapping and crossover experiments, and computational studies.

  • Reductive Reformatsky-Honda Reaction of α,β-Unsaturated Esters: Facile Formation of 1,3-Dicarbonyl Compounds and β-Hydroxy Esters

    The reaction of tris(triphenylphosphine)rhodium chloride [RhCl(PPh3)3] with diethylzinc (Et2Zn) easily afforded a rhodium-hydride complex that effects the 1,4-reduction of α,β-unsaturated esters to give rhodium enolates. Formation of the rhodium enolate is followed by transmetalation with the zinc species to give a Reformatsky-type reagent, and this reacts with various acid chlorides at the α-position
    三(三苯基膦)氯化铑[RhCl(PPh 3)3 ]与二乙基锌(Et 2 Zn)的反应容易得到氢化铑络合物,该络合物可实现α,β-不饱和酯的1,4-还原,从而得到烯醇铑。 。形成烯醇铑后,与锌物种进行金属转移以形成Reformatsky型试剂,该试剂在α位与各种酰氯反应生成β-酮酸酯。Reformatsky型试剂还可以与各种亲电子试剂(如醛,酮和酸酐)反应,得到相应的产物,其中亲电试剂在α,β-不饱和酯的α-位被还原性引入。

    Compounds containing a substituted or unsubstituted allyl group directly bound to a chiral carbon atom are prepared enantioselectively. Starting reactants are either chiral or achiral, and may or may not contain an attached allyloxycarbonyl group as a substituent. Chiral ligands are employed, along with transition metal catalysts. The methods of the invention are effective in providing enantioconvergent allylation of chiral molecules.

    The synthesis of chiral, nonracemic difluoromethylthio (SCF2H) compounds that contain a tetrasubstituted stereogenic center is reported. Racemic α-SCF2H-β-ketoallylesters 5 were initially prepared by an electrophilic difluoromethylthiolation of β-ketoallylesters 6, followed by a Pd-catalyzed Tsuji decarboxylative asymmetric allylic alkylation (DAAA) to provide a wide variety of chiral, nonracemic α-
