  Total synthesis of the pyranocoumaronochromone lupinalbin H

  摘要：

  The pyranocoumaronochromone lupinalbin H was synthesized in three major steps, which involved preparation of 2'-hydroxygenistein by the Suzuki-Miyaura reaction, followed by oxidative cyclodehydrogenation into lupinalbin A. The final step was the regiospecific introduction of the dimethylpyran moiety to ring A of lupinalbin A via an aldol-type condensation with 3-methyl-2-butenal and 6 pi-electrocyclization.

  4 ' ,5,7-Trihydroxy- or 8-alkyl-4 ' .5,7-trihvclroxycoumaronochromones were synthesized by oxidative cyclization of the corresponding 2 ' -hydroxyisoflavones with o-chloranil under mild conditions. By contrast, alkoxycoumaronochromones were synthesized by oxidative cyclization of the corresponding 2 ' -hydroxyisoflavones with DDQ. (C) 2001 Elsevier Science Ltd. All rights reserved.
• Constrained phytoestrogens and analogues as ERβ selective ligands
  作者：Chris P Miller、Michael D Collini、Heather A Harris

  DOI：10.1016/s0960-894x(03)00394-9

  日期：2003.7

  A new series of ERbeta (ERbeta) selective ligands has been prepared. One of the compounds 6, structurally related to the phytoestrogen apigenin 4, displays a binding preference for ERbeta over ERalpha of over 40-fold. In addition to its binding selectivity, 6 was able to potently induce metallothionein (an ERbeta specific response in human SAOS-2 cells) while demonstrating low potency in an ERalpha dependant ERE-tk luciferase assay in MCF-7 cells. Such receptor and cell selectivity could make 6 a useful molecular probe for better understanding the role of ERbeta in mammalian physiology. (C) 2003 Elsevier Science Ltd. All rights reserved.
