  The formal oxidative addition of electron-rich transoid dienes to bromonaphthoquinones

  摘要：

  This work established the idea that a halogen atom, such as bromine, will act as a control element in the regiospecific formation of a new carbon-carbon bond. The addition of the electron-rich end of a transoid diene to a bromojuglone derivative occurred exclusively at the unsubstituted carbon of the quinone. Thus, 2,2-dimethyl-4-methoxy-6-methylene-1,3-dioxa-2-sila-4-cyclohexene (3) and either 2- or 3-bromo-5-hydroxy-1,4-naphthoquinone (1 or 2) afforded the adducts 19 or 20 in 57% or 71% yield. Similarly, 2,2-dimethyl-6-methylene-4-(trimethylsiloxy)-1,3-diox-4-ene (4) and 1 gave 21 in 77% yield.

  A newly developed experimental technique, based on colorimetric interferometry, has allowed accurate measurement of central and minimum elastohydrodynamic (EHD) film thickness for a wide range of operating conditions. This study was aimed at determining the influence of various material parameters on central and minimum EHD film thicknesses. Obtained experimental data were compared with Hamrock and

• Divergent Approach to the Bisanthraquinone Natural Products: Total Synthesis of (<i>S</i>)-Bisoranjidiol and Derivatives from Binaphtho-<i>para</i>-quinones

  日期：2013.1.18

  development of the first asymmetric synthesis of a chiral anthraquinone dimer is outlined, resulting in the first total synthesis of (S)-bisoranjidiol. Rather than a biomimetic dimerization retrosynthetic disconnection, the anthracenyl ring systems are generated after formation of the axially chiral binaphthalene framework. This synthetic strategy has enabled the synthesis of several analogues. Key
