• Palladium-catalyzed benzylic-like nucleophilic substitution of benzofuran-, benzothiophene- and indole-based substrates by dimethyl malonate anion
  作者：Gaëlle Primault、Jean-Yves Legros、Jean-Claude Fiaud

  The palladium-catalyzed benzylic-like nucleophilic substitution of acetates derived from benzofuran, benzothiophene and indole was investigated. The asymmetric substitution on racemic 1-(2-benzofuryl)ethyl acetate gave disappointing results, but the substitution product was obtained in 98% ee from (S)-1-(2-benzofuryl)ethyl acetate with overall retention of configuration.

  研究了钯催化的衍生自苯并呋喃，苯并噻吩和吲哚的乙酸酯的苄基样亲核取代。外消旋的1-（2-苯并呋喃基）乙酸乙酯的不对称取代反应令人失望，但取代产物是由（S）-1-（2-苯并呋喃基）乙酸乙酯以98％ee的形式得到的，且保留了构型。
• A new structural alternative in benzo[b]furans for antimicrobial activity

  Two series of 2-substituted and three new diacetyl benzofurans were synthesized through palladium-catalyzed reactions, and their in vitro antimicrobial spectra were assessed. The compounds demonstrated mild to significant growth inhibition against antibiotic-susceptible standard and clinically isolated strains of Gram-positive and Gram-negative bacteria as well as human fungal pathogens. Ampicillin and kanamycin were used as references for antibacterial screening; nystatin and amphotericin B were used for antifungal screening. Varying substitution at the benzofuran moiety and subsequent antimicrobial screening identified the C-3-acetyl functionality as a new structural alternative for optimal antimicrobial property in the benzofuran class of Compounds.

  carboalkoxylation, hydroamination, and carboamination reactions of alkynes, effecting the formation of substituted benzo[b]furan, indole-, and isochromene-1-one derivatives, respectively. This procedure allows for the transfer of (substituted) allyl, methoxymethyl (MOM), benzyloxymethyl (BOM), and (trimethylsilyl)ethoxymethyl (SEM) groups from oxygen to carbon and is compatible with functional groups
