Intramolecular competition reactions were carried out on substrates having an increasing number of deuterium atoms at symmetry-related sites. Products that arise from peroxyl radical abstraction at each position of the various substrates reflect the competition rates for H(D) abstraction. The primary KIE for

  • Use of Deuterium Labeling Studies to Determine the Stereochemical Outcome of Palladium Migrations during an Asymmetric Intermolecular Heck Reaction
    作者:Bronwen M. M. Wheatley、Brian A. Keay
    DOI:10.1021/jo071119u
    日期:2007.9.1
    [GRAPHICS]A series of deuterium labeling experiments showed that Pd migrations during an intermolecular asymmetric Heck reaction between phenyl triflate and various deuterated 2,3-dihydrofurans (2b, 2c, 2d, 2e) occurs exclusively by either syn-1,2-dyotropic shifts or a syn-chain-walking mechanism; no evidence was observed to support anti-1,2-dyotropic shifts or anti-beta-H Pd eliminations during the formation of 6 and 7.
  • A Convenient Route to the Synthesis of Isotopomeric Dihydro-2(3H)furanones
    作者:Piero Frediani、Luca Rosi、Marco Frediani、Gianluca Bartolucci、Massimo Bambagiotti-Alberti
    DOI:10.1021/jf070305y
    日期:2007.5.1
    A general synthetic procedure leading to isotopomeric dihydro-2(3H)furanones (gamma-butyrolactones) containing two, four, or six deuterium atoms has been developed. The labeled dihydro-2(3H)furanones were synthesized in quantitative yield from the saturated diacid C-4 (succinic) or unsaturated diacids C-4 (fumaric, maleic, or acetylendicarboxylic) in the presence of Ru4H4(CO)(8)(PBu3)(4) using a deuterium pressure of 180 bar at 180 degrees C. This methodology was applied to the total synthesis of a hexadeuterated matairesinol lignan: The 3,4-bis[3-methoxy-4-(phenylmethoxy)phenyl]methyl}dihydro-2(3H)furanone-[7,7',8,8',9',9'-D-6] (benzyl-protected matairesinol-D-6) was fully characterized.
