• Efficient construction of the core framework of lysidicin A via three Claisen rearrangements including a cascade reaction

  日期：2010.6

  A model compound (6) with the core skeleton of lysidicin A was synthesized as a racemate. The key step (8,7) includes three Claisen rearrangements of the triether with phloroglucinols; two of which rearranged in a cascade manner and the other was a simple rearrangement. This one-pot reaction enabled the introduction of three phloroglucinol units at the correct positions and makes the synthetic approach significantly efficient. (C) 2010 Elsevier Ltd.
