  (R)-3-(2-Chloro-3-hydroxy-4-methoxy-phenyl)-3-hydroxy-N-[(E)-3-iodo-4-(4-methoxy-benzyloxy)-but-2-enyl]-propionamide 在 2,6-二甲基吡啶 、 tris(dibenzylideneacetone)dipalladium(0) chloroform complex 、 copper(l) iodide 、 N,N-二异丙基乙胺 、 cesium fluoride 作用下， 以 二氯甲烷 、 N,N-二甲基甲酰胺 为溶剂， 反应 27.0h， 生成 (1R,8R,20R,21R)-8,20,21-tris[[tert-butyl(dimethyl)silyl]oxy]-24-chloro-4-methoxy-14-[(4-methoxyphenyl)methoxymethyl]-2-oxa-11-azapentacyclo[11.8.2.13,7.016,22.017,21]tetracosa-3,5,7(24),13(23),14,16(22),17-heptaen-10-one

  Convergent approach to the maduropeptin chromophore: aryl ether formation of (R)-3-aryl-3-hydroxypropanamide and cyclization of macrolactam

  摘要：

  Efficient enantioselective syntheses of the functionalized phenol and diethynylcyclopentene moiety of the maduropeptin chromophore were achieved. Their CsF-mediated coupling yielded a sterically congested aryl propargyl ether. The subsequent intramolecular Sonogashira coupling reaction between the vinyl iodide and diethynyl groups occurred at the appropriate position to yield a macrolactam, which was accompanied by Pd-mediated enyne-yne benzarmulation.
