  A concise synthesis of maleic anhydride and maleimide natural products found in Antrodia camphorata

  摘要：

  Recently, the natural products maleic anhydride I and maleimides 2 and 3 have been isolated from the mycelium of Antrodia Camphorata, each displaying activity in LLC cell lines. We describe a concise synthesis of each of these natural compounds utilizing C-C cross-coupling methodology, namely, the Negishi and Suzuki reactions. This efficient and high yielding synthesis is convergent lending itself to production of medicinal analogues. (c) 2007 Elsevier Ltd. All rights reserved.
