3-Acyloxy-2-phenalkylpropyl amides and esters of homovanillic acid as novel vanilloid receptor agonists
摘要:
A series of 3-acyloxy-2-phenalkylpropyl amides and esters of homovanillic acid were designed and synthesized as vanilloid receptor agonists containing the three principal pharmacophores of resiniferatoxin. Amide analogues 23, 5 and II were found to be potent agonists in vanilloid receptor assay both for ligand binding and for activation. (C) 1999 Elsevier Science Ltd. All rights reserved.

A mild and efficient regioselective reductive opening of methoxybenzylidene acetals using a combination of Bu3SnH and MgBr2. OEt2, mainly via five-membered chelation intermediates is described. This reaction was applied to synthetic intermediates of myriaporon and tedanolide. (C) 2000 Elsevier Science Ltd. All rights reserved.
