  Cyclotrimerization of unsymmetrically bromo-substituted diynes: toward the synthesis of potential selective inhibitors of tyrosine kinase 2

  摘要：

  A study on transition metal catalyzed alkyne cyclotrimerization of unsymmetrically bromo-substituted diynes with ethynyltrimethylsilane was carried out to prepare bicyclic bromobenzene key intermediates for the total synthesis of five potential tyrosine kinase 2 inhibitors. Two different pre-catalysts (Cp*RuCl(cod) and [Rh(cod)(2)]BF4/BINAP) and different reaction conditions have been examined. (C) 2012 Elsevier Ltd. All rights reserved.

  日期：2013.9

  Cyclotrimerizations of ethynyl N-methyliminodiacetic acid (MIDA) boronate (1) with 1,6-diynes 2 have been studied, using three different catalysts (based on ruthenium, rhodium, and iridium) and variable reaction conditions. Successful cyclotrimerization reactions were obtained with both Cp*RuCl(cod) and Rh(cod)2BF4/BINAP as pre-catalysts in THF or acetone. Ruthenium-catalyzed cyclotrimerization of
