  名称：

  A chemoenzymatic and enantioselective total synthesis of the resorcylic acid lactone L-783,290, the trans-isomer of L-783,277

  摘要：

  The structure, 5, assigned to the resorcylic acid lactone L-783,290 has been prepared for the first time and in a modular fashion using a Heck reaction to link the readily available fragments 8 and 14. Chemoenzymatic methods were used to prepare the latter fragment, in enantiopure form, from chlorobenzene. (C) 2009 Elsevier Ltd. All rights reserved.
