An enyne metathesis/Diels–Alder reaction sequence towards the synthesis of cup-shaped 5/5/6-tricyclic architectures
摘要:
A strategy to synthesize the 5/5/6-tricyclic framework of presilphiperfolane natural products is described, involving a model dienyne compound (1). The key steps are an enyne metathesis reaction to introduce the diene part and a Diels-Alder cycloaddition to reveal the tricyclic architecture. (c) 2007 Elsevier Ltd. All rights reserved.
