Palladium-Catalyzed Cross-Coupling of Ethyl Bromodifluoroacetate with Aryl Bromides or Triflates and Cross-Coupling of Ethyl Bromofluoroacetate with Aryl Iodides

10.1021/acs.orglett.7b00938

Tingting Xia, Lei He, Yahu A. Liu, John F. Hartwig, and Xuebin Liao present a novel palladium-catalyzed Negishi cross-coupling reaction for constructing C(sp2)-CF2 and C(sp2)-CHF bonds using ethyl bromodifluoroacetate and ethyl bromofluoroacetate, respectively. The study describes a method to couple ethyl bromodifluoroacetate with aryl bromides and triflates under mild conditions without the need for organozinc reagent preparation, representing the first conversion of aryl triflates into products containing C-CF2 bonds. Additionally, the cross-coupling of aryl iodides with ethyl bromofluoroacetate was achieved under similar conditions to form a-aryl monofluoro esters in good yields. The optimized reaction conditions, using [Pd(p-cinnamyl)Cl]2 as the catalyst precursor and Xantphos as the ligand in THF solvent with TBAB as an additive, resulted in high yields for a broad range of aryl bromides and triflates. The study also demonstrated the versatility of the synthesized ethyl aryldifluoroacetates as precursors for further transformations into various compounds containing a CF2 unit.

Synthesis of L-4,4-difluoroglutamic acid via nucleophilic addition to a chiral aldehyde

10.1021/jo015754q

The research focuses on the synthesis of L-4,4-difluoroglutamic acid, a fluorine-containing derivative of amino acids that is increasingly important for probing biological functions and enzyme mechanisms. The study presents a new, flexible route to enantiomerically pure L-4,4-difluoroglutamic acid, utilizing the addition of difluorinated nucleophiles to configurationally stable R-aminoaldehydes. The process involves several steps, including Barton-McCombie dehydroxylation and acid hydrolysis, to convert difluorinated adducts into the desired amino acid. Key chemicals used in this synthesis include 1,1-bis(dimethylamino)-2,2-difluoroethene, ethyl bromodifluoroacetate, Reformatsky reagent, and various protecting groups such as the 9-phenylfluoren-9-yl group.
