  Synthesis of the Reported Structure of the Bisbenzoquinone Lanciaquinone, Isolated from Maesa lanceolata

  摘要：

  Lanciaquinone, isolated from Maesa lanceolata, was originally assigned as a bisbenzoquinone with a C-14-chain linking the two quinone rings. A synthesis of the reported structure, in which the key step is a double Claisen rearrangement, suggests that the structure of the natural product needs to be revised.

• Benzoquinone derivatives of Myrsine africana and Maesa lanceolata

  日期：2003.10

  The fruits of Myrsine africana afforded two new benzoquinone derivatives, methylvilangin and methylanhydrovilangin. On the other hand, from the fruits of Maesa lanceolata two more novel compounds; 2,5-dihydroxy-3-(nonadec-14-enyl)-benzoquinone and lanciaquinone were isolated. Their structural elucidation was achieved by spectroscopic measurements including 2D NMR experiments. (C) 2003 Elsevier Ltd. All rights reserved.
