  Synthesis and SAR study of N-(4-hydroxy-3-(2-hydroxynaphthalene-1-yl)phenyl)-arylsulfonamides: Heat shock protein 90 (Hsp90) inhibitors with submicromolar activity in an in vitro assay

  摘要：

  Heat shock protein 90 is emerging as an important target in cancer chemotherapy. In a program directed toward identifying novel chemical probes for Hsp90, we found N-(4-hydroxy-3-(2-hydroxynaphthalene-1-yl)phenyl)benzene sulfonamide as an Hsp90 inhibitor with very weak activity. In this report, we present a new and general method for the synthesis of a variety of analogs around this scaffold, and discuss their structure-activity relationships. (C) 2008 Elsevier Ltd.

  Synthesis of Unsymmetrical o-Biphenols and o-Binaphthols via Silicon-Tethered Pd-Catalyzed C−H Arylation

  摘要：

  A mild, practical, and efficient method for the synthesis of unsymmetrical o-biphenols (including o-phenol-naphthols and o-binaphthols) has been developed. Unsymmetrical bis-aryloxy silanes, which were readily prepared in a semi-one-pot fashion, underwent the Pd-catalyzed intramolecular arylation followed by a routine TBAF desilylation step to furnish valuable unsymmetrical biphenols without necessity of isolation of seven-membered intermediates. The excellent functional group tolerance allows for synthesis of a variety of functionalized o-biphenols and o-binaphthols from easily available staring materials.

• Phenoxenium ions identical intermediates in the acid-catalyzed solvolysis of n-tosyl-O-Arylhydroxylamines and in the thermolysis of N-Aryloxypyridinium salts

  The acid-catalyzed solvolysis of N-tosyl-O-arylhydroxylamines in aromatic solvents and the thermolysis of N-arylqxypyridinium salts involve common intermediates, phenoxenium ions, for the formation of hydroxybiphenyl derivatives. Diphenylethers are formed when the hydrolysis of the N—O bonds is slow and the aromatic solvent has high nucleophilicity.
