  Methodology for the synthesis of 1,2-disubstituted arylnaphthalenes from α-tetralones

  摘要：

  alpha-Tetralones were initially converted into 1-bromo-dihydronaphthalene-2-carbaldehydes and 1-bromo-naphthalene-2carbaldehydes. These precursors were then subjected to Suzuki coupling reactions to afford 1,2-disubstituted aryldihydronaphthalenes and 1,2-disubstituted arylnaphthalenes, respectively. The former products were oxidized with DDQ to give 1,2-disubstituted arylnaphthalenes. (c) 2006 Elsevier Ltd. All rights reserved.
