  • 2,3-Disubstituted and 2,3,5-Trisubstituted Benzofurans by Regioselective Pd-Catalyzed Cross-coupling Reactions; a Short Synthesis of Eupomatenoid-15
    作者:Thorsten Bach、Marc Bartels
    DOI:10.1055/s-2001-16052
    日期:——
    2,3-Dibromobenzofuran (1) and 2,3,5-tribromobenzofuran (2) undergo regioselective Sonogashira- and Negishi-type cross-coupling reactions at the 2-position. Subsequent substitution reactions at C-3 are possible for the cross-coupling products obtained from compound 1. A regioselective functionalization of the 3,5-dibromobenzofurans derived from substrate 2 was achieved by an halogen-metal exchange which occurred selectively at the 3-position. In a conclusive reaction step cross-coupling reactions at C-5 were used to build up 2,3,5-trisubstituted benzofurans. As an example, the synthesis of eupomatenoid-15 (8) is described.
    2,3-二溴苯并呋喃(1)和2,3,5-三溴苯并呋喃(2)在2-位点进行区域选择性的Sonogashira型和Negishi型交叉偶联反应。从化合物1得到的交叉偶联产物在C-3位可以进行后续取代反应。通过对2来自底物2的3,5-二溴苯并呋喃进行区域选择性功能化,实现了在3-位点选择性发生卤素-金属交换。在最终的反应步骤中,利用C-5位的交叉偶联反应构建了2,3,5-三取代的苯并呋喃。作为一个例子,描述了eupomatenoid-15(8)的合成。
  • Synthesis of eupomatenoids by three consecutive transition metal-catalyzed cross-coupling reactions
    作者:Thorsten Bach、Marc Bartels
    DOI:10.1016/s0040-4039(02)02287-6
    日期:2002.12
    Six different eupomatenoids (1a-c, 1f-h) were prepared from 2,3,5-tribroinobenzofuran (2) in a concise and high-yielding synthetic sequence. The overall yields vary between 29 and 60% over four to six steps. Key to the success of the syntheses is the high regioselectivity achieved in three Pd(0)- and Ni(0)-catalyzed cross-coupling reactions which were conducted consecutively. The order of substitution at the benzofuran nucleus is C-2, C-5 and C-3. (C) 2002 Elsevier Science Ltd. All rights reserved.
