  Synthesis of 9-substituted xanthenes by the condensation of arynes with ortho-hydroxychalcones

  摘要：

  The reaction of o-(trimethylsilyl)aryl triflates, CsF, and o-hydroxychalcones affords a general and efficient way to prepare biologically interesting 9-substituted xanthenes. This chemistry presumably proceeds by the tandem intermolecular nucleophilic attack of the phenoxide of the chalcone on the aryne and subsequent intramolecular Michael addition. The introduction of an external base, Cs2CO3, has proven beneficial in this reaction. (c) 2012 Elsevier Ltd. All rights reserved.

  Structural simplification of the core moieties of obeline and ergoline somatostatin sst(1) receptor antagonists, followed by systematic optimization, led to the identification of novel, highly potent and selective sst(1) receptor antagonists. These achiral, non-peptidic compounds are easily prepared and show promising PK properties in rodents. (C) 2009 Elsevier Ltd. All rights reserved.
