  Synthesis and RNase A inhibition study of C2-symmetric bis-isochromenyl sulfones

  摘要：

  A new class of C-2-symmetric bis-isochromene derivatives with 3,3'-linkage has been synthesized from bis-propargyl sulfones. The method involves treatment of the sulfones with triethylamine to form the isochromene derivatives presumably via the intramolecular Michael addition to the intermediate bis-allenic sulfones. Interestingly, the product expected from the Garratt-Braverman pathway was not obtained. The bis-isochromene 7d displayed RNase A inhibition activity, much stronger than the isochromene 8 and bis-isocoumarin 9. (C) 2010 Elsevier Ltd. All rights reserved.
