  Compounds from Danshen. Part 7. Regioselective introduction of carbon-3 substituents to 5-alkyl-7-methoxy-2-phenylbenzo[b]furans: synthesis of a novel adenosine A1 receptor ligand and its derivatives

  摘要：

  By maintaining the balance between the electronic requirements, the stereochemical restrictions as well as the kinetic and thermodynamic factors, the unprecedented regioselective electrophilic aromatic substitution of formyl and nitro groups to carbon-3 of 5-alkyl-7-methoxy-2-phenylbenzo[b]furans have been achieved. Subsequent transformation of the resulting formyl group into methyl, hydroxymethyl, 1-hydroxyethyl, and cyano groups are also described.

  A new synthesis of the benzofuran adenosine antagonist XH-14

  摘要：

  5-(3-HydroxypropyI)-7-methoxy-2-(3'-methoxy-4'-hydroxyphenyl)benzo[b]furan-3-carbaldehyde (XH-14, 1) has been reported to be a potent A(1) adenosine antagonist. We have developed an efficient synthesis of this compound that should prove valuable for further structure-activity studies. The synthesis incorporates optimised methodology for the selective protection of a hydroxyl group and the ortho-bromination of a phenol. (C) 1997 Published by Elsevier Science Ltd.

  A naturally occurring benzofuran, namely 5-(3-hydroxypropyl)-7-methoxy-2-(3′-methoxy-4′-hydroxyphenyl)-3-benzo[b]furancarbaldehyde was isolated from the roots of S. miltiorrhiza Bunge “Danshen”. Its structure was established by means of spectroscopic methods as well as by a total synthesis. Both the natural and the synthetic compounds showed a high potency (IC50 = 17 nM and 10 nM, respectively) in
