  A fast and straightforward route towards the synthesis of the lissoclimide class of anti-tumour agents

  摘要：

  The synthesis of the chiral core structure of the lissoclimide class of anti-tumour agents containing three rings including a chiral succinimide subunit and an exocyclic double bond has been investigated The compound 7 was obtained without the use of any protecting groups for the alcohol at C-12 via an asymmetric boron-mediated aldol addition as the key step to install the chiral centres of the rare succimmido methanol moiety This was followed by a sequence of lactonisation microwave-assisted amidation and imidation reactions (C) 2010 Elsevier Ltd All rights reserved
