The Electrocyclization of Heptatrienyl Anions

Synthesis DOI: 10.1055/s-0040-1720086 The thermal electrocyclization of heptatrienyl anions is reviewed. We begin with a succinct background on the importance of cycloheptane rings in complex molecules and a brief survey of approaches to their synthesis. We also review the fundamental aspects of this electrocyclization manifold, relying on the Woodward–Hoffmann rules for pericyclic chemistry. Then we survey the literature, covering the burst of discovery in the late 1960s and early 1970s, and the more sporadic reports in from the 1990s to the present day.1 Introduction2 The Electrocyclization of Heptatrienyl Anions3 Discovery and Early Development (1964–1975)4 Recent Developments (1996–2023)5 Concluding Remarks [...] Georg Thieme Verlag KG Rüdigerstraße 14, 70469 Stuttgart, GermanyArticle in Thieme eJournals: Table of contents  |  Abstract  |  Full text
