摘要：
The synthesis of the allelochemical heliannuol C I is described by employing a Bargellini condensation and a Claisen rearrangement to install the gem-dimethyl and vinyl functionalities, respectively. A Dieckmann cyclisation of diester 11 enabled the generation of the benzoxepane ring system enshrined in 1. (c) 2006 Elsevier Ltd. All rights reserved.
